SeaMonkey Add-on Compatibility Tracking

Starting with SeaMonkey 2.7, all add-ons that are declared compatible with at least SeaMonkey 2.1 will work out of the box ("compatible-by-default"), i.e. you do not need to install additional add-ons or change preferences to make these work. Add-ons with binary components (like Lightning and Enigmail) and special add-ons (themes, dictionaries etc.) are exceptions to the rule.

Recent Changes to This Page

Please list any major changes here (latest first, max. three visible entries, max. one entry per day and contributor)

• 2015-04-15 Results for SeaMonkey 2.33 and later, with detailed comments for SeaMonkey Add-on converter
• 2013-08-22 David Ross Added Fontinfo to Section 1.6.
• 2013-08-21 David Ross In Section 1.6: added info regarding BetterPrivacy (this entry corrected 2013-9-19)

General Notes

• This Wiki replaces SeaMonkey/2.1/AddonCompat in an attempt to make the information relevant without being tied to a specific SeaMonkey version.
• Since this is a Wiki page, anyone with an account can modify it. If you have need an add-on being checked, please add it to the Discussion page instead of this one. Thanks!
• For each add-on, only the basic functionality has been checked.
• Please don't make the below a table. The goal is to have this as short and easily editable as possible.
• "AMO" means addons.mozilla.org. "xsidebar site" includes: modified / modifiedmisc / modifiedmailnews
• Please do not add very seldom-used add-ons, themes, dictionaries etc.
• Please double-check your findings before adding to any of the below lists.
• When adding add-ons, please check for versions in this order:
  1. AMO (including experimental ones)
  2. external sources (versions that work without modifications)
  3. AMO versions that only need a compatibility override
  4. other versions that only need a compatibility override
  5. any versions that need SeaMonkey added to install.rdf
• Some add-ons might be listed as compatible at AMO but not feature compatibility in the install.rdf of the XPI file. For such add-ons, AMO sends a compatibility override signal to SeaMonkey's add-ons back-end. Affected add-ons can only be installed if either an Internet connection exists or the Add-on Compatibility Reporter add-on is installed and enabled. However, add-ons that include neither SeaMonkey nor Toolkit in their install.rdf at all cannot be installed either way (bug 680845) and need to be listed under "Needs Addition to install.rdf".

Add-ons available from AMO, by SeaMonkey release version

Notes:

1. Please list the highest supported full release. Examples: 2.6a2 → 2.5, 2.8a1 → 2.7.
2. Please list only names (except experimental versions), since versions may change.
3. If an add-on listed in this section is compatible with a previous version of SeaMonkey, you can enable it after installing the Add-on Compatibility Reporter (ACR) add-on. (Then be sure to check that it actually works!)

2.33 (and later)

A Click on the ⓘ will lead you to the Mozilla Add-on Compatibility Data Base. A Click on ► will directly lead to conversion of the add-on.

Compatible

Even if an Add-on from AMO can be installed and works, although it has been tagged Not available for SeaMonkey on AMO, it might be advisable to use a Converted version, because Add-On-converter adds some additional changes.

Converted Version Compatible

Addon compatible after having used Firefox & Thunderbird Add-on Converter for SeaMonkey
Even if an Add-on from AMO can be installed and works, although it has been tagged Not available for SeaMonkey on AMO, it might be advisable to use a Converted version, because Add-On-converter adds some additional changes.

A Click onConvert ► will directly lead to conversion of the add-on. Since May 2015 the converted add-ons show "[converted]" in add-on manager between name and version.

• Adblock Plus Pop-up Addon 0.9.2 — Convert ►  (Adblock Plus Pop-up Addon extends the blocking functionality of Adblock Plus to those annoying pop-up windows that open on mouse clicks and other user actions.)
• ErrorZilla Plus 1.2.4 — Convert ► (Provides more useful error message page if page for URL can not be found)
• Show Password 1.7 — Convert ► (Allows to make visible password while typing)
• YouTube mp3 1.0.9 — Convert ► (Adds a button to any YouTube Movie what will start mp3-converter for that movie). Converted Add-on for download available on sourceforge.net at SeaMonkey Add-ons Project.
• WOT 20131030 — Convert ►   (User ratings for safety of Websites)

Converted Version NOT Compatible

• Add-on Compatibility Reporter 2.0.5 (Allows to report add-on compatibility issues): No "Report Issue" buttons shown in German Seamonkey 2.33 Build 20150308222025 on German WIN7 64bit
• BugDigger — Convert ►  ⓘ  (Collects bug report information)
• Reddit Enhancement Suite 4.5.4 (A suite of tools to enhance Reddit)   ⓘ 
• StumbleUpon 1.16 (Collects Websites matching with user's interests), seems to work fine after conversion, but suspect: weblinks from email will no longer work from email client with this converted add-on installed.

Converted Versions still need review

(seem to work more or less due to results on mozillaZine Add-On-Converter page)

• Turn Off the Lights — Convert ►
• QuickWiki — Convert ► (works but some js errors in console)
• Empty Cache Button — Convert ►
• Google Translator for Firefox — Convert ►
• Text Link — Convert ►
• Fast Dial 4.12 — Convert ► works partially
• ReloadEvery — Convert ► works but context menu on tabs doesn't appear
• NoSquint — Convert ► partly
• BlockSite — Convert ► partly - password protection doesn't work
• Color Transform — Convert ►
• easy Xdebug — Convert ► - SM support is formally included but this add-on is very old and will benefit from this tool
• Easy Copy — Convert ►
• DictionarySearch — Convert ►
• fontinfo — Convert ► - partly: Page Info window will be a bit broken - convert without porting Page Info features (in options) to keep right-click context menu feature only without breaking Page Info. You may also be interested in converting Font Finder.
• Disconnect — Convert ►
• Textarea Cache — Convert ►
• Unhide Passwords — Convert ►
• Context Search — Convert ►
• Multicolumn Bookmarks - Note: this extension has been removed by the author and is known not to work with SM 2.29 and later
• CoLT 2.6.4 (short for "Copy Link Text") — Convert ►
• Menu Icons Plus 3.0 — Convert ► - works but because menu items in Firefox don't always overlap with those in SM not all of them will get an icon
• Menu Mod 2.2 — Convert ► - almost: option to display menus as one letter doesn't work; an error in console shows up - test if this addon doesn't break anything else
• Konquefox 1.8.2 — Convert ►
• Image Toolbar 0.6.15 — Convert ►
• FireTitle 0.5.5-1 — Convert ►
• Domain Details 2.7 — Convert ►
• Remove It Permanently 1.0.6.10 — Convert ► - status bar icon doesn't show up and can mess up items positioned to either side, but all other features seem to work
• Resurrect Pages 2.0.6 — Convert ►
• New tab toolbar button 1.1 — Convert ►
• Close Button 0.4.1 — Convert ► - almost: when close button is set to close tab then it will not close window when there are no more tabs, regardless of settings
• Tiny Menu 2.0.4 — Convert ► - tip: it appears you can't move the "tiny menu" to other toolbars but you can move items from other toolbars to the the "tiny menu" toolbar therefore ending up with one sleek toolbar that saves space - this works even better than in Fx 29 (where location bar seems to be unmovable)
• Tab Focus 1.0.8 — Convert ►
• Flashblock 1.5.17 — Convert ►
• Toolbar Buttons 1.0 - this extension supports SeaMonkey natively since version 1.0.1 - no need to convert!
• SaveLink 3.2 — Convert ►
• Notepad (QuickFox) 2.8.4 — Convert ► - seems to work, however not all features have been tested
• EHTip 2.4.4 — Convert ►
• Shumway — Convert ►

• Organize Status Bar (Revived) 0.1.0 — Convert ►
• SpeechUtil 0.3 — Convert ►

• Capture & Print 0.1.9.2 — Convert ►
• Stacked Inspector 1.0.20110524 — Convert ►

• Search by Image for Google 1.2.0 — Convert ►
• Greasemonkey 2.3 — Convert ► - default script editor is not available - set up external editor in options to make the edit function work. Otherwise it appears to work but has not been thoroughly tested. You can also consider Scriptish, a GM fork, which supports SeaMonkey natively (use "Install Anyway" button if it appears as not available for SeaMonkey). Another alternative: Greasemonkey Port.
• Quick Context Search 1.5.2 — Convert ►
• Yet Another Context Search 1.3.1 — Convert ►
• ProfileSwitcher 1.6.2 — Convert ►

• pastego 2.0.4 — Convert ►
• Key config 0.3.1 — Convert ► - partly: most configurations work but there are a few actions that do not. This extension is made for a very old version of SM and will hence benefit from conversion.
• Memory Restart 1.18 — Convert ► - generally appears to work, however after the selected memory limit is reached it starts throwing js errors in console, hence this extension may have some hidden issues in SeaMonkey
• Google Translator, Web Translation, ImTranslator 8.3 — Convert ►
• Drag & DropZones 1.6.1 — Convert ►
• Cache Status 0.8.5 — Convert ► - tip: in options enable forcing placement of UI in status bar - then this extension will place itself in SeaMonkey's status bar
• Exit Button Firefox 0.4.2 — Convert ►
• Exit Button Thunderbird 0.5 — Convert ► - note: this and Exit Button Firefox will not cooperate together so choose only one
• Custom Tab Width 1.0.1 — Convert ► - note: this extension will not restore default widths on disabling or uninstallation
• Search Highlight 1.0.1 — Convert ►
• Pale Moon Commander 1.5.0 — Convert ► - warning: while this extension appears to work in SeaMonkey it is for advances users only and can break things if tinkering with hidden settings, especially that some settings do not work in SM or work differently than in Fx/Pale Moon. Only partially compatible. Use with caution.
• Progre 1.0.2 — Convert ► - caveat: this extension will prevent "Paste & Go" context menu item from appearing
• Page Zoom Button 1.4.1 — Convert ►
• Zoomr 1.1 — Convert ►
• Bottom Error Console 0.3.4 — Convert ►
• Navigate Up 2.6 — Convert ►
• Dir Up 1.0.17 — Convert ►

• Image Picker 1.9.3 — Convert ►
• Save Images 1.1.0 — Convert ► (this appears to be adapted to SM and can be installed without conversion but still the conversion helps with some minor issues)
• Blank Your Monitor + Easy Reading 1.9.11 — Convert ►
• I don't care about cookies 2.3.5 — Convert ► - right-click menu entry "Report a cookie warning" does not work
• Video Downloader professional 1.97.36 — Convert ►
• Inspect Context 1.00 — Convert ►
• Awesome Screenshot Plus - Capture, Annotate & More 2.4.6 — Convert ► (requires SM 2.33 or later) - current version 2.4.4 has broken file saving, even in Firefox, please use version 2.4.5 - currently in version history — .. Install 2.4.5 ..
