Error message: the bookmarks and history system will no be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I tried following the directions in "learn more" but to no avail. Please help this senior citizen get his bookmarks back! Thank you.

When I access the website of UGC ( https://www.ugc.fr/ ) the access page opens up but immediately freezes: the screen luminosity decreases and the pointer cease to function: I cannot acces any of the options: select movies on show, select cinema programmes or schedule, open my UGC account to reserve performances ... Nothing works ... I have tried to reduceprotecton, etc as sugested on Forum and other suggestions: nothing works. I have no problem at all when I open the same website with Opera or with Microsoft Edge ... Why it does not work under Firefox puzzles me. Can you do something about it ? I use Firefox as my defaut internet access without problems for everything else ! This is really strange and most annoying. Thanks for your help.

I decided to uninstall Firefox and l re-installed it from scratch and i still get the same error message.

Thunderbird refuses colored text on new Lenovo 17" Idealpad and adds asterisks not written by the author. Example message test: bbbbbbbbbbbbsssssssss ggggggggggggg***234*5678,56 *<==============* The written numbers and the arrow were colored red. No asterisks were written in the message sent. When writing, colors appeared correctly in messages with no asterisks on screen. However, no colors appear and asterisks are added in recorded messages sent and received on the PC. The Lenovo PC works OK in general, so it must be a Thunderbird configuration/function problem on my PC as the message is correctly received with colors without asterisks on my mobile phone. Can you help me correct this PC anomaly? Many thanks

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

This is a brand new problem, for me. It just started today when using FireFox. On nearly all websites, including Mozilla support, when I click on an embedded link on a site, firefox asks me to select an app to open the https. Even if I tell it to let firefox open all https, it still asks me everytime. to make it better, it still doesn't always let me open the link and I go through the same thing when I click the link again.

This also happens when clicking on the search box in *any* search engine, e.g. Google, Startpage

See the image below.

I've attempted to change all cookie & tracking settings, no help. I even uninstalled and reinstalled Firefox.

This is making FireFox useless.

I had to use my default browser, Brave, just to submit this question. I only use FireFox for social media accounts, sites I need to link to my sm accounts and the occasional web search. For example, linking my Etsy shop to facebook. When I clicked the link "link to facebook" is when I noticed this problem.

I upgraded from windows 10 to 11 My son was able to recover my e-mail folders, but some large folders are missing and the remainder only have e-mails from 2019 or earlier. How do I recover those e-mails? I am no longer conversant with the current technology or terminology. I need simplistic instructions.

I have installed Thunderbird with Zorin 18 and it won't show contacts. Google says that Thunderbird has full access to contacts. Attempt to manually add contacts fails with message of "Can't connect to server". I did have to manually add the calendar to make that part work. Is this an uninstall and reinstall (Thunderbird that is) situation?

Thanks for your help

I have never ever had a problem getting into my bank account until this evening.

Says it is insecure.

How can this happen? I really need to get into my account!
