When browsing, I sometimes (more often than not) get a Secure Connection Failed message. The Try Again tab clears the problem sometimes (not that often). This problem has just started happening in the last week, during which I have not made changes to any settings in Firefox. This problem does not exist using other search engines for the same site that I am trying to access, and I note that I also get this same failure when trying to access some Firefox webpages. Is there a fix to this other than contacting the web site owner, which I doubt is the cause of the problem, or for ease and simplicity should I just change to another search engine that does not have the problem?

I use Thunderbird on Windows and on Mac. I'm wondering why the startup time on Mac is significantly longer on MacOS. I'm currently on Tahoe 26.0.1 but Thunderbird has always been a slow starter. Can I change any setting to remedy this. At the moment I have two mail accounts configured both Gmail.

I went away for a few days and when I came back I was missing a bunch of local folders. I THINK one of my employees kids were banging on me keyboard. I know I should not allow them in my office or at least password my computer when I go away??

I could import from an old computer and at least have all the local folders from before I changed computers 2 years ago.     I have a feeling there maybe an easier way?

Running on a mac. ventura. 13.2.1 thunderbird 140.3.1esr (aarch64) thank you for any help.

A long time ago I was able to set the max number of rows for shortcuts on the Firefox home page to 5. Sometime fairly recently it has changed to 4. I don't know why nor can I remember which line in about;config I used to change it. I think the line was "browser.newtabpage.activity-stream.topSitesRows" but when I try to change it, it does nothing. At the time I first changed it, the max it would change to was 5. The max now appears to be 4 if I did it correctly. Your help would be appreciated.

On Windows 11 laptops, I am currently using an Acer Nitro w/ 12th gen Intel i5 16GB RAM, I use my touch pad for scrolling on sites with infinite scrolling. Occasionally this function breaks, when it does it breaks for every tab in the browser window including the setting, I haven't found a singular or specific cause yet. I have troubleshooted it in the community, the prevailing logic being that themes or extensions are causing some incompatibility, so I have reset everything to defaults and made sure I have no extensions loaded, and the problem persists. I can temporarily fix the issue by going into my settings and turning hardware acceleration on and off again. I am writing this to hopefully point out this bug as clearly as possible in hopes that your programmers can fix it in a future update, as repeatedly turning a setting on and off to "fix" it might not be the best solution in the long term.

Have updated from 140.3.1 esr 32 bit to 143.0.1 release 64 bit TB and to windows 11 - uninstalled 32 bit and installed 64 bit and updated to windows 11 Following updates found that device sign in id (pin) was used to be in 32 bit missing from settings to access password but can show passwords. In reviewing the profile after update I note that Mozilla location service key, google location service key and safe browsing keys are missing (not sure what they were pre update). The key4.db file pre update was 1/3/22 but after update it is 10/10/25. The logins.json pre and post update is 7/9/25. I can see the default release profile and local only - use only the default release. My question is - has the 64 bit installation cleared all my keys/how can I check all my keys and how do I fix and ensure connections are secure?

Thankyou for any advice.

I want to continue using TB but a few things really make me despair of it. But there may be workarounds. If I have a question, when did these people last send me an email, or have any of these people responded to something, there seems to be no way to get to a list. But. I found a way to do it. Using sqlite3.

I have been wanting a CLI for interacting with TB for a while. You know, that folder I have with 10k+ emails and if I click on it, the UI spins forever. What is even in that?

Now I can do this: 1) copy the global-messages-db.sqlite from the active profile to another place 2) run: sqlite3 global-messages-db.sqlite 3) ```sqlite> select m1.c3author, min(m2.date), max(m2.date) from messagesText_content m1, messages m2 where m1.docid = m2.id group by m1.c3author order by m1.c3author; ... ray kiddy <ray@ganymede.org>|1732124816000000|1759268233000000 ruby29@something undefined|1756740716000000|1756740716000000 salvatore@someother undefined|1758733831000000|1758733831000000 support@linode.com undefined|1755126295000000|1755126295000000 ... ```

Holy sender dates, Batman! Now I can see the earliest and latest email sent by any user. Now I can filter, sort, and see every person who sent me something in a time period. And whether it was 1 email or 1000, I just see the names and not an enormous amount of other information.

So, is this the only way to get this? Or the best? I have no idea. Please let me know if there is a better way, perhaps one using TB itself. It would be nice.

In the meantime, I will be wrapping this in a python call, doing some formatting and it will work and I can stop worrying about not seeing their email.

MacOS 26.0.1 Tahoe Firefox 143.0.4 (aarch64)

There is a white border around the webpage content in the browser (screenshot attached). This border exists even in troubleshooting mode, with all extensions disabled, regardless of toolbars or theme, etc. The only place it does not appear is the about: pages (screenshot attached). I've uninstalled and reinstalled Firefox and updated MacOS. The issue disappears when I quit and reopen Firefox but reappears when I resize the window. Is there some obvious checkbox setting I'm missing? I cannot figure out what is causing this. Thanks for any help.
