I just tried to open Firefox and got the 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". DO NOT redirect to this link

It is useless. I tried to restore 3953 items from a previous back up and received the message "Unable to process the backup file".

I am not interested in hearing how to prevent this problem in the future, because obviously creating backups do not work.

How do I check to see if the problem was caused by security software, even though I have not added anything?

I've disabled all of my addons, cleared cache, and still youtube is broken for me. It works fine with Chrome still. Any ideas on how to fix? See attched screenshot.

After the recent update I am no longer permitted to stream movies. How can I reverse this update, change it or will there be a patch to address this malfunction? I am not the only one that this has happened to. Every update changes my settings, I have learned to go back into settings and change back.

Warun habe ich Version 115 und auf einem anderen PC und Laptop die Version 128. Alle behaupten ich hätte die neueste Version.Hauptproblem ist, daß seit dem 1.8.2024, 17.16 Uhr auf dem PC mit der Version 115 die Symbolleiste und alle Lesezeichen verschwunden sind. Vierenscanner habe ich deaktiviert. Gruß Gundi

Not sure why this https://support.mozilla.org/en-US/questions/1400794 was archived.

Being archived I cannot "check mark" the question to show I too have this problem.

It is a basic problem and a piece of gravel in the shoe of many, I suggest, Firefox users who are developers.

Clearly, there is a need for a UI to navigate inspected content results and the original question author was exactly correct.

This is drip by drip making me want to end my return to Firefox and give up and use Chrome.

Even just an indication such as unarchiving the riginal post and linking to a "Pending to fix" Github issue would be a nice step.

Thank you Mozilla for all you do, and here's hoping this will get looked at.

I still have not had any improvement with tab crashes especially on sites containing videos. Lately, every time i go on Facebook and play a video reel, i stop the video and before i can return to my home page, the tab crashes. This browser has gotten worse rather than improving.

why everytime i use firefox the default web address is: https://hao.360.com/?src=lm&ls=n077c1cd59a

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

Hello! A year or two ago I ran into a problem. While Firefox is checking for an update, it does not load any sites. I have to wait about 5 minutes each time before I can start using the browser. It is incredibly annoying. Has anyone encountered this kind of problem?

Using Firefox for webmail, There used to be an option to spellcheck a "Composed" message before sending it. Probably after a recent "upgrade", that option seems to have disappeared. True? Can I get the facility back in some way?

I'm hoping to get some help with disabling the Insecure connection password warning in Firefox version 115.11.0.

In previous versions, I could disable this warning through the about:config settings. However, I couldn't find the specific setting (security.insecure_field_warning.contextual.enabled) that was mentioned in some online resources.

I understand the security risks involved in disabling these warnings, and I only intend to do this on a trusted website on my local network.

Could you please advise on the best approach for achieving this in Firefox 115.11.0, or any alternative solutions to manage insecure connection warnings for trusted local sites?

Thanks in advance for your help!

I cannot begin to express how frustrating this change is... and I struggle to comprehend why anyone would introduce this by writing it into software, but I'm sure it has something to do with money and profits.

There was a time when you could do a search and get a list of results, and then view a specific listing, and then return to your search page and view another listing. however, those days are evidently gone, as now when you return to your search page, it's slightly different results in a different order. Most are there, but some are missing entirely, and the ones that remain are varied slightly. Whaaaat for!? It is truly a form of torture.

Now in fairness I can't tell if it's the browser (Firefox), or the search engine (Duck Duck Go), because I am unfortunately not a developer. However, whatever is causing it should be fixed out of a sense of social responsibility to the greater good.

If anyone knows why this happens and knows how to fix it, I would be sincerely grateful if you shared the solution.

Firefox uses about half a gig on my disk, that's: '~/.mozilla' and '~/.cache/mozilla' can that be reduced? Either some setting that limits disk use or even a manual deletion of ancient stuff?
