FireFox Browser messed up my Internet Download Manager and made it impossible to copy and paste from MS WORD to my emails. Once I uninstalled IDM, I was able to copy and paste. I could not even open a picture in another TAB as before. So the browser was updated and messed everything up. I tried the MS EDGE browser, and it functioned like FireFox browser use to as of today.

See the subject. I've been seeing delays in launching for several months. I've run several windows defender malware checks (full and the one where it runs outside of anything brought up). I've reset firefox. I did all this also because I was seeing random ads from a news site from what they were trying to get me to do was install macafee (but it's malware). While I'm not seeing those ads now and I'm suspicious they can from the news site vs. my browser, I'm very aware of anything trying to capture screen scrapes. I'm even considering changing all my passwords as I'm not sure if anything was captured. This morning, firefox upon launch took a long time. Then it said installing updates. My desktop flashed and firefox launched. I have not installed anything or any addons, extensions, etc. So either this was firefox doing an update it needed or it's something else. I'm on windows 10.

My Firefox program was recently re-installed by Dell. But it seems to be an older version and among other things I can't find my bookmark toolbar. So I'm hoping that updating Firefox will solver this problem.

Firefox keeps making me restart nearly every day. I had a form I was trying to fill out and because of the restart I lost it 4 times! How many updates are you doing "in the background" that opening a new tab tells me to restart and then I lose stuff. Surely you are not updating every day.

I got an eMail notification about an upcoming update for Thunderbird snap/flatpak configs, but I don't see any entry for Thunderbird in my "~/.var/app/" directory. There is an entry for Firefox, but nothing for Thunderbird. Yet Thunderbird still updates regularly and successfully.

What should I do, in order to conform to the eMail notification instructions?

Dell recently re-installed my Firefox program but it seems to be an older version. Although I can find my bookmarks the bookmark toolbar is gone and that was a very handy feature. How do I update the program and get my toolbar back?

a,most weekly when I try to open a new tab I'm told an update started in the background and I need to restart firefox to continue working. I can't open any new tabs or go to a new website unless I restart. Is there a way to run updates on MY Schedule rather than having this happen. a notice that an update is ready to be installed rather than per-emotively just starting one would be polite and appreciated.. Just 'starting' it in the background without telling me makes you guys look like Microsoft rather than Mozilla.

My Firefox browser has just been updated .. not by me but somehow .. to 140.11.Oesr(64-bit) Its completely messed up all my settings .. why? Its taken me the best part of this morning to sort everything out . All my bookmarks were not displayed, the web pages that should have been displayed on startup weren't.. and to cap it all the "Done" button is hidden at the bottom of the page .. and why is it needed  ? all other setting just need to be changed to set them. Its so annoyed me that I've downloaded Chrome. and I'm using Opensuse Leap!

I'm running Thunderbird 128.8.0esr 64bit. I see that many extensions are saying that they work on versions including 137. I see that the newest release is 136.0, which has at least one feature I like: a way to globally set threaded or unthreaded messages. What about 137? Is it still in beta. Is either one of these worth upgrading from 128? Thanks!

I opened Thunderbird 140.9.1esr from flatpak on Debian 12 and today I noticed a message that says: "Flatpak ESR application ID change We're switching the Flatpak ESR application ID from org.mozilla.Thunderbird to org.mozilla.thunderbord_esr."

1. How does Thunderbird know it's flatpak name is changing? How do i turn off all auto updates including checking things like flatpak name changing?

Hello! After donating, I am still hit with campaign prompts through the Update server. How do I stop these (now annoying) messages? Thanks!

Dear Mozilla Firefox Team,

I hope this message finds you well.

We manage a network of workstations that frequently utilize the Mozilla Firefox browser. Recently, we have encountered a situation where many of our systems are showing vulnerabilities due to pending browser updates. The updates are being installed successfully; however, users often neglect to restart the browser, which is crucial for completing the update process and ensuring security.

To address this, we would like to inquire if there is an existing Group Policy that can be configured to automatically notify users when they need to restart their Firefox browser to apply the latest updates. Such a feature would greatly assist us in maintaining the security integrity of our workstations and ensuring that users are made aware of the importance of restarting their browsers when prompted.

If this functionality is not currently available, we would appreciate any insights on potential workarounds or future plans to incorporate such a feature.

Thank you for your attention to this matter. We look forward to your response.
