Tab Mix Plus does not work properly

If you are reading this page, you have probably encountered a problem with Tab Mix Plus. While it can be some unknown bug, most issues reported in the forum usually end up being extensions or theme conflicts.

In order to identify and solve the problem there are several things you can do.

Install latest development version

First, install the latest development version to see if the problem might have been fixed (there's always a development build sticky thread in the Builds forum). You can reinstall the latest official version in place of the development version later if you wish.

If the latest development version still has the problem then the place to post about it is the development build sticky thread in the Builds forum, but before you post there are a few more things to try.

Create new testing profile

Create a new profile (Creating new profile is safe and doesn't have any effect on your current profile, which you can return to using once you complete testing the new profile), install Tab Mix Plus and import your preferences from the problematic profile. If you don't see the problem, it's most likely a conflict with another extension. Install your extensions one by one restarting in between until the issue reappears (once you isolate the conflicting extension(s), you don't have to use the new profile unless you want to).

Disable other extensions

If you prefer not to create a new profile for testing, you can try disabling your other extensions in the current profile instead. Then enable each extension one by one and test for the problem.

Note: This is not as good as creating a clean profile because the conflict may be an option choice or another customization made in the browser and not another extension.

If you have a high number of extensions, a way to expedite this troubleshooting is to disable half of the installed extensions at a time. If the problem disappears, then you know that the conflicting extension is one of those you just disabled.

If this is still a high number of extensions, you can enable half of those extensions and check for the problem. If and when you get to a more manageable number of extensions, you can then enable/disable extensions one at a time until you isolate the one conflicting with Tab Mix Plus.

Reset your profile

Finally, if nothing else works you can reset your profile, read the article Reset Firefox - easily fix most problems from Mozilla support.

Report your finding

When you finish your testing, we encourage you to report about your findings, whether you find the culprit or not, to our forum, so other users can benefit from your findings and to help Tab Mix Plus developers to solve the issue you have. (Read How to post about a problem). In the case the conflict is another extension or theme, please report about it to the developer of the conflicting extension or theme also so that they can work it out as well.
