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.

Hi All:

I just got a new laptop and so I am getting everything set up the way that I like it. I have come across a problem with my sidebar though. I like to keep my bookmarks up all the time, but I want them to not be too wide and take up a lot of my screen. On this new computer, there's an addition 5 cms or so of white space at the far left of the tool bar. It had different buttons on it up at the top (one of them had something to do with AI) and a little gear down at the bottom of the space. I was able to remove all of the buttons up at the top, but I can't seem to hide the whole thing. I just want to see my bookmarks, without that extra customization sidebar. Is there a way to hide the spot highlighted in pink, but still have the bookmarks visible?

As I mentioned I can't seem to access my network folders. I only have this issue in this machine but I have my account on 3 different machines on the network with no issues. All have the same extensions and settings.

All of a sudden, my Yahoo Mail Contacts doesn't load. The following is the error message where my contacts should be listed. How do I fix this? Thank you

I use Firefox (the current version) on a Dell Windows 11 Pro laptop. I have around 8800 bookmarks, and I've lost around half the tags on my bookmarks. (The bookmarks themselves are OK; I'm losing about half of the tabs.,) This has happened to me twice recently, and I'm restoring the bookmarks as I write these words.(after I'm finished, I'll save two copies of the HTML file for backups. Can anybody tell me why this is happpening, aaand How I can prevent it in the future?

Thanks.

Hi,

I was super pumped about profiles but it seems it has gone terribly wrong for me.

I created a two profiles on one computer and would like to reuse them on another. Apparently this is impossible, which is really too bad, please change that! Why would I want to redo everything on every computer that I work with? And it deleted bookmarks on other computers synched to my account, why?

And I deleted every profile on one of my computers, in the hopes to "start fresh" since I had lost all my work, and now Firefox refuses to open. It indicates "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

So now I need to re-install the whole app. Just... Why?

Thanks!

I did a clean install of Windows and downloaded Firefox, but after signing in and pressing sync none of my old bookmarks or anything is showing up. Is it gone now? I did not have Firefox on any other device.

I am running a desktop with Win 11 pro with all the updates. I have Firefox as my web browser and Thunderbird for my email accounts, Talktalk, Aol and gmail. When I try to open a web page with a mailto link, although Firefox is set as default it will not open the link, oddly it will work with gmail. I do not have this problem with my other desktop running Win 7. How do I get it to work on Win 11. Please note I am a 80 year old and totally illiterate computerwise. Therefore I need the answer to be step by step and when you say open this or that please tell me how to open it. Geoff

Onshape starts ok and displays all page toolbars and the graphics correctly for around 3 to 7 seconds then it all goes blank for several seconds and then only the toolbars etc return. The graphics for the model disappears along with the camera view which shows where the model is in x y and z and also the camera does not move with the right mouse button pressed. See pics below:

L to R - Proof of model existing although not shown in work area

          - Additional proof of 2nd model not showing in work area
          - Actual screen after the display blanks and reappears

It also happens in all web pages but the data comes back, Onshape is the only cloud based App I am currently trying to use. I did install a Xerox print service recently and that needed a .NET update (3.5), after that these problems started. I have uninstalled and reinstalled Firefox from the Mozilla site which cured the problem at the time but it has since returned.

I want to make list of sites where i can off pop-up search bar. On some sites you can use custom hot keys (like youtube), but hot keys won`t work because your keys registering to pop-up search bar instead site, so it will be good idea to make exclusion list, like in addon "Dark Reader".

Can one change the colour of one firefox window to distinguish it from another firefox window? That would allow two people working on the same computer to use individual firefox windows and be able to quickly tell whether they are in the right window.
