Known Issues

This list covers some of the known problems with SeaMonkey 2.17 Beta 1. Please read this before reporting any new bugs.
- Data loss warning: If you use a profile with this or any later version and then try to go back to SeaMonkey 2.0, SeaMonkey will rename your history file to places.sqlite.corrupt and create a new places.sqlite file, effectively resetting your browsing history. This is because the internal format changed and the upgrade process only works in one direction. Additionally, running MailNews with local folders and POP3 mail filters may produce summary files that are not correctly read by previous versions of SeaMonkey. If you decide to go back to a previous version of SeaMonkey, you should delete the .msf files for your local folders and POP3 accounts or repair the folders using the folder properties dialog in order to avoid potential data loss.
- You may experience a busy cursor in MailNews while reading news (bug 727414).
- After creating a news account through clicking a news URL, the MailNews account wizard may be broken (the account type will always be News). To work around the problem, set the mail.server.serverX.valid pref (where X is the internal number of the corresponding news account) to true in about:config, or delete the invalid news account (bug 521861).
- Web pages may appear differently in the MailNews feed reader than in the browser (bug 662907). Workaround: Add a "noscript {display:none}" rule to your userContent.css (note that the Stylish add-on cannot be used here since it does not integrate with the MailNews feed reader).
- Select Element by Click doesn´t flash the element in DOM Inspector on Windows if hardware acceleration is enabled (bug 594299).
- The option "When opening a bookmark group" / "Replace existing tabs" under Preferences / Tabbed Browsing does not have an effect anymore (bug 664101).
- Lightning options cannot be opened from the Add-ons Manager. Instead, Lightning preferences can be accessed from Preferences/Lightning (bug 636104).
- Lightning keyboard shortcuts for accessing the calendar tab from within the MailNews window or from the main menu (Ctrl+Shift+C/D) do not work. (bug 514512).
- If you try to start SeaMonkey using a locked profile, it will crash (see bug 573369).
- For some users, scrolling in the main GMail window will be slower than usual (see bug 579260).
- Some synaptic touch pads are unable to vertical scroll (see bug 622410).
- Under certain conditions, scrolling and text input may be jerky (see bug 711900).


Norton/Symantec anti-virus scanners may report that some parts of SeaMonkey (e.g. the file freebl3.dll) are suspicious. If you downloaded SeaMonkey from one of the official download sites, this is a false alarm. You might experience problems with secure websites when this happens. To fix the issue, instruct your anti-virus software to ignore these files (and move them out of quarantine) and/or switch to another anti-virus software and reinstall SeaMonkey.


The Oracle Java 7 plugin does not work with SeaMonkey (bug 754622).
The cursor may change to "drag & drop" mode in the mail window, causing a hang (bug 736811).


When hardware acceleration is off, background colors in the UI (toolbar, status bar etc.) might not update correctly when you switch focus from/to a window. Users running Macs with certain older hardware (e.g. Intel GMA 950) will experience this even if they haven´t turned off hardware acceleration in Preferences (Appearance/Content) (bug 626096).


- Some questions are asked more frequently than others. Have a look at the SeaMonkey FAQ. Maybe your particular problem has already been solved.
- Some anti-virus software keeps detecting our installers as containing a "Trojan" or "Downloader". This is a false positive and is some wrong detection mechanism in the anti-virus software. The code in question is actually from 7-Zip and decompresses the installer so that its contents can run and install SeaMonkey. That technology is widely used and probably can be used to compress bad as well as good software, but the 7-Zip code itself is perfectly safe. Mozilla scans all our files routinely when putting them on the FTP server and we assure you that our installers are as clean as the official Firefox downloads that are scanned by the same mechanisms.
- Poorly designed or incompatible extensions can cause problems with SeaMonkey, including make it crash, slow down page display, etc. If you encounter strange problems relating to parts of SeaMonkey no longer working, the browser not starting, windows with strange or distorted appearance, degraded performance, etc, you may be suffering from Extension or Theme trouble. Restart SeaMonkey in Safe Mode. On Windows, start using the "Safe Mode" shortcut created in your Start menu or by running seamonkey.exe -safe-mode. On Linux, start with ./seamonkey -safe-mode and on Mac OS X, run:

cd /Applications/

./seamonkey-bin -safe-mode

When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.
- If you uninstall an extension that is installed with your user profile (i.e. you installed it from a Web page) and then wish to install it for all user profiles using the -install-global-extension command line flag, you must restart SeaMonkey once to cleanse the profile extensions datasource of traces of that extension before installing with the switch. If you do not do this you may end up with a jammed entry in the Extensions list and will be unable to install the extension globally.
- If you encounter strange problems relating to bookmarks, downloads, window placement, toolbars, history, or other settings, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running SeaMonkey with the -P command line argument, choose the "Manage Profiles" button and then choose "Create Profile...". Migrate your settings files (Bookmarks, Saved Passwords, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file.
