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.

For the last few weeks I have been unable to save new bookmarks into the folder of my choice. Instead I can only save new bookmarks into the last folder I created. I cannot navigate to a different pre-existing folder. This problem only occurs when using Firefox on my Android cell phone, but not on my PC. However, I can still view and use all of my previous folders and bookmarks when wishing to open a new website, per usual. Thank you

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 ...

The newest update 144.0.1 now has numbers next to bookmark folders. I don't need nor want this info. How do I disable this setting?

Hello. I haven't been able to find anything of the sort on my own, so i fear maybe there is no actual way other than doing it one by one. But, is there a way to add all of my currently open tabs in firefox android app, to my bookmarks (or collections, maybe), instead of having to select them one by one? Or, in its defect, a way to select all tabs, given that there seems to be no button to quickly select all currently open tabs? At this point, if anyone knows a firefox extension/add-on that works on mobile that could do that, i would deeply appreciate it.

Thanks in advance, i just want a way to not have to select my 100+ open tabs by hand since it genuinely seems like a waste of effort for me and i would rather spend that energy into migrating to another browser altoghether.

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"

I've used Firefox a long time on different platforms, bookmarks get duplicated, irrelevant and numerous for the same websites.

When I try to rationalize them the workflow does not allow me to easily bin the superfluous ones without opening the site and then only removes the title not the web address.

The computer work flow is much better but as mobiles are now more frequently used as main devices, would it not be sensible to change this behaviour for a better workflow?

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

The newest update now has numbers next to my bookmark folders telling me how many bookmarks I have. I don't need nor want this info. How do I disable this setting?

I hate more clutter with updates.

I'm a heavy bookmark user. I have numerous bookmark folders and numerous bookmarks within each folder. I love the way the desktop version (Firefox for Windows) allows for easy sort and save for bookmarks. I absolutely hate the way Firefox for Android handles bookmarks. There is no way to sort and no way to choose a default save folder.

Awhile back a change was made to Firefox for Android. Before the change, saving all new bookmarks automatically saved them in the root Bookmarks folder where they were easy to grab and reassign to a particular folder. After the change, bookmarks now get saved in the last folder used.

This causes problems with later finding bookmarks when they were saved in a folder that wasn't expected and is especially troublesome when you have numerous bookmark folders. For example, I had been saving bookmarks in the root Bookmarks folder. Every once in awhile I go through that folder and move bookmarks I want to keep into other folders. Whichever folder I last moved a bookmark to now becomes the default save folder. The next time I save a bookmark it goes to that last used folder. If I don't remember which folder it was, now I have to search. Or I have to remember and be fast enough to hit "Edit" on the small pop up window that shows up after saving a bookmark.

But it gets worse. I recently went through my bookmarks and moved several from the root bookmarks folder into other folders. I later saved a bookmark and had to go find it in one of the sub folders. After finding it, I moved it back to the root Bookmarks folder. Let's call it "Bookmark A". Fast forward several weeks where all subsequent bookmarks were saved in the root Bookmarks folder as I desired. I then went through all my bookmarks and deleted those I no longer needed. This time I didn't move any of them. BUT, the last bookmark I deleted was "Bookmark A". The next time I saved a bookmark, it did not get saved in the root Bookmarks folder as I expected. I had to go find it again in the same sub folder where "Bookmark A" was originally saved. Apparently, when I deleted "Bookmark A", Firefox for Android somehow remembered the next most recently used folder. I hate this so much!

Can we get a setting to define a certain folder as the default folder for future saved bookmarks?

I don't understand the reason for the change in the first place. But, if there are plenty of users who want bookmarks automatically saved in the last used folder, then give everyone a setting to either choose that method or a default saved bookmark location.

I'd also like to see a drag and drop method to sort bookmarks as well as settings to sort by name, date, etc.

I'm running the latest version of Firefox for Android on a Samsung S25.

Fix saving bookmarks like it a) was earlier. You select wanted folder from the list.

b) alternatively, in settings where you can select folder where save bookmark always saves (instead of last used, in windows, Linux, android...). This would be the best option.

Showing all bookmarks and folders all at once when saving a bookmark is beyond frustrating to use every time and it’s unnecessary. Please make folders selectable individually like they are on most other browsers with bookmarks rather than having to have all the bookmarks out at once. Maybe make it so pressing it opens and closes the folder, and holding it will put a bookmark in that folder. Or just have it so in bookmark saving mode, tapping/pressing the folder opens the folder, there’s a back arrow to get out of the folder, and a “save here” button or something on the other side of the back button to save the selected bookmark to whatever folder you are in. It’s not like that interferes with moving folders and bookmarks since you have to press the edit button before you can move those first anyway.

Hello. Good morning. Bookmark management in the mobile version is very strange. As far as I can tell, managing bookmarks in folders and subfolders is almost impossible and unusable. Thank you for sharing your wealth of knowledge with us for so many years. I wish you to continue to be useful and cool for humanity.
