I'm getting the following error message:

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I don't know what prompted this concern on my Windows 11-based laptop, but I only noticed this last night doing some research for another issue. I don't have any of my bookmarks showing up in the bookmarks section, nor will it allow me to click the star on any tab to bookmark the page. I have restarted and shut down my laptop several times and this is not solving the concern. Let me know if you need more information or if I need to start this inquiry again elsewhere, but again it sounds like the same concern.

I have included a screenshot of the exact error for accuracy's sake. Like everyone else here, I'm trying to get my bookmark and history access back up and running but not sure how to go about it.

I couldn't get past the first fix suggestion because I am not sure how to restart Firefox (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US). I have restarted my laptop several times but the issue still persists.

Please advise.

Ironically, I am not having this issue on my older PC that is still operating on Windows 10. I can view history and access or add bookmarks with no concern to my knowledge.

icon is missing on 2 of my bookmark, tried every fix found on google and AI and nothing works ... you should add a simple fonction to choose an icon for the bookmarks ...

I have been with Mozilla since Netscape 1. Recently, I have been unable to add or delete a bookmark or folder. A number of previous bookmarks have lost their icons and their content. The Bookmark "Star" turns blue, indicating that it has been bookmarked. When I look for it in the designated folder it is not there. I try to edit garbled bookmark URLs by substituting the new URL - does not work. There are a number of folders for categories of bookmarks and I cannot delete them. What can be done?

To eliminate multiple problems (including disappearance of bookmarks) in desperation I uninstalled and cleared out all remnants of FF, then installed a new FF. Fortunately I had recently imported all the stuff FF more recently lost into MS Edge so I used the FF feature to import from MS Edge. However, every effort to import my bookmarks failed. So I used MS Edge's ability to create a HTML file of my bookmarks and then in FF used the "import a HTML file" feature to get them into FF. However, FF fails to recognize my bookmarks as bookmarks. It lists them in a "Favorites Bar" which cannot be strewn horizontally across the top of my screen as did my bookmarks in the past nor be viewed as bookmarks.

So HOW can I get FF to change the "Favorites" into Bookmarks?

In the tiny image I've uploaded, IF it can be read, the Bookmarks selections are "empty"

my bookmark bar disappered suddenly and all my tabs are gone. i tried to bookmark a new tab but it would not let me. and i didnt do anything different. opened my laptop today and i had to restore all tabs, and my bookmark bar is gone and all my shortcuts from bookmarks are gone too

Hello, I noticed google rolled out new icons for its workspace. However I use these workspace apps frequently and leave them on my bookmarks bar. For some reason however the docs, slides, and sheets logos respectively have defaulted their icons back to the original google drive icon. making it impossible to tell which is which from a glance. Sorry to bother y'all!

I have tried to bookmark websites recently and cannot. Once the star in the web address turns blue the pop up scree will appear. I hit the save button and the website does not bookmark in the file created for say 'news' bookmarks. I tried with other websites/bookmark files. Nothing seems to be happening.

After the last few Firefox updates, my bookmarks will not work at all. I have never had these issues before the last few updates, but they're quite aggravating. Is there an easy way to fix this issue where it does not happen again?

It looks like now Firefox bookmarks every page I visit. This is not right! I only want to bookmark pages I explicity request to be bookmarked. How can we fix this?

Now that some bright person eliminated my visible bookmarks, I find firefox is just too hard to use. You eliminated my bookmarks from the screen, but they are still there in the menu. Problem is, I have too little patience to use the bookmarks menu EVERY TIME, OVER AND OVER.

So the Firefox team has forced me to Bing. That sucks. I think this update was a tragedy for USERS, but users never matter anyway, so who cares? NOT FIREFOX. This last update ruined Firefox in my humble opinion.

Don't bother to reply. I'm leaving in disgust. Good luck, y'all!
