testing fixes

Test new features and fixes in the most stable pre-release build of Thunderbird.

Whether you are just curious or already using beta, this reference will help you have the best possible experience. Beta is a great choice if you want to help the global Thunderbird community by testing fixes and new features, and discovering and reporting bugs before they reach release. Thank you for your interest in using beta! [[UI:details_start]] === Read these important considerations about using beta === * Protect your Thunderbird data by doing regular [[Profiles - Where Thunderbird stores your messages and other user data#w_backing-up-a-profile|backups of your Thunderbird profile]]. * New features may require time to complete and polish, so flaws are to be expected. But we do want to hear about them. Use the beta forum to learn about new features and user experience. * Low-impact flaws may not be fixed quickly, because bugs are prioritized based on many criteria. Patience is a good quality to have when using beta. * High-impact flaws such as data loss are very rare but may occur. Protect yourself with backups. * Expect frequent updates - typically seven per month. This frequency of updates allows us to make fast improvements. * Beta installation will replace your currently installed program, unless you use the instructions in How to install and run Beta. * Are you using POP accounts? Unlike IMAP accounts, the only copy of your pop mail is in your local Thunderbird profile. If you want to add a POP account to beta, your options are: * After set up, go to ≡ > Account Settings > Server Settings and make sure the "Leave messages on server" option is checked, and the "For at most [X] days" option is unchecked. Keep the default settings. Messages will be removed from the server 14 days after download, so you will need to either stay on beta, or learn how to move your POP data back to the release profile. * If you have mail filters that, for example, move mail to local folders, then you must decide where to run filters - in your beta profile or your other profile. * Some of your add-ons may not work. Or if they do work today, they may not work tomorrow. Add-on authors are not obligated to make their add-ons work in beta, but please submit your issues to help prepare them for new releases. Consult the [[Thunderbird add-ons - frequently asked questions#w_what-if-my-add-on-is-broken|Add-ons FAQ]] if you have difficulty.

For now, please ask for assistance in support. --> = How do I change from a beta version back to a release version? = How you change back to a release version depends on how you configured your profile data, and when you decide to make the change. If you only have one profile, then the best time to change is shortly before or within two to three weeks after a major version ships publicly, like when version 115 ships and the beta is still version 116. This timing will minimize the possibility that data structures have changed. You have two options: # Beta program installed in its own directory, beta data is in a [[Dedicated profile per Thunderbird installation|dedicated profile]], and you do not need any beta data (address books, local folders, pop folders, etc.) back in your production profile, and wish to remove the beta data and beta program from your system: <!-- copied from https://www.thunderbird.net/en-US/download/beta/#uninstall --> #* Start the release version of Thunderbird to use the [[Using Multiple Profiles|profile manager]]. #* Delete the beta profile using the profile manager, default name is “default-beta”. #* Delete the beta version’s program directory in your OS. # Beta program installed in its own directory, beta data is in a [[Dedicated profile per Thunderbird installation|dedicated profile]], but you DO need beta data (address books, local folders, pop folders, etc.) copied back to your production profile. '''This gets messy and difficult, and is something you really want to avoid.''' #* While running beta, export your address book(s) to file(s) as vCard, which you can then import into version 91 (but version 91's lower capabilities might mean the results will be less than perfect). #* Open both of your profiles in your OS's file browser. One way of finding them is {button ≡} > {menu Help} > {menu Troubleshooting Information} > {menu about:profiles}. #* Shutdown both versions of Thunderbird. #* [[Profiles - Where Thunderbird stores your messages and other user data#w_restoring-a-profile-backup|Backup your production profile]]. #* Under the '''Mail''' directory you will find both '''Local Folders''' directory and pop account directories – you can copy the contents of these from the beta profile to your production profile, taking care to NOT overwrite any msgFilters.dat files (which contain your filter rules) in your production profile. #* Imap accounts – there should be no need to copy any files from beta profile to your production profile. = Beta isn't for me.
