Firefox Community Forum

Everything was fine until about an hour ago. Suddenly over half My tabs quit working. Either the display is weird and all text, or the page is blank, or there is a small "broken image" icon in the upper left... A few tabs are working fine. On X I get a notice saying, "Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com."

I tried turning off tracking (which was NOT "strict!!!"), and that did not fix the problem.

What is going one????

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

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

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?

For weeks I have been trying to find a solution to getting "Error 15" on certain websites when using Firefox. Opera and Edge have no problems with those sites, only Firefox has problems. I have tried every "fix" that I can find on the Mozilla site and none of them work. Is there anything else I should try before I abandon Firefox? Could it be that Firefox is now unreliable under Win7 Pro 64-bit? If so I will have to abandon it because this computer cannot run Win10 or later.

Hi, I'm a Firefox user since around 2004. Whenever I used FF i always opened multiple windows of FF. At some point Mozilla came out with Tabs. I don't use them and as a matter of fact I use the option under settings to open links in a new window (not tabs). Always have, Why? Habit I guess from the times I first starting using FF. I seriously don't use Tabs. I would like to Remove the Tab Bar from FF because of this reason and it frees up a lot of visual space on my browser. I've spent hours reading/searching/trying on "how" to remove or at least hide the Tab Bar. Waste of time so far, so I decided to Post the Question.

How Do I Hide or Remove the Tab Bar in FireFox?

Thanks For Everyone's Help in Advance:-)

Firefox currently blocks port 10080 to protect against a presumed security threat. Linksys routers use port 10080 to allow users to log in to the guest network so Firefox has rendered Guest Network logins to be unaccessable forcing router owner to allow "guests" to log in to the the primary lan and potentially cause issues with the very network they are trying to protect from outside issues. Firefox needs to provide a way for guests to log into the guest network within their software... particularly in the ios and android versions of the Firefox apps. Please provide a reasonable workaround so that I don't put my network at risk by allowing guests to log in to my primary network.

I don't know if breakage is the correct topic. I keep Ring.com open to the dashboard in a pinned tab. A few days ago, I had viewed and cleared videos as usual and later returned to view new activity. The site requires logging in every 30 days and so seeing that I needed to do so was not a surprise. What was a surprise was that the login buttons were grayed out. I closed the tab, cleared the Ring cookies and cache and tried again. No luck. I wondered if there was some other setting that I didn't know about and decided to open a private window and try it there. To my surprise, it works. I'm stumped. I'll attach the raw data from the private window as a .txt file. Darn. I can only attach an image. Well, I have it available and can copy and paste it into a subsequent post if you think it would help

I'm using Windows 7 and have been migrated to the esr updates for Firefox. I think this problem started cropping up just before going to the esr versions, but not sure. Firefox will a) randomly hang and do nothing for 5-10 minutes and then pick up fine b) tends to hang a lot when signing into websites like banks, etc, doing the same thing as (a). I've updated FF several times since then, but same problem. I did try to do 1 fix which suggested creating a new "places" database, but that did not solve the problem. Not sure where to go from here as nothing has changed on my computer since the problem started - no new software, etc.

FOLLOWUP: Success! It turned out to be an extension called "Enhancer for YouTube". I added that because my add-ons had been wiped out by the update yesterday and forgot that it was a new one I'd never tried before.

Thank you Cor-el for pointing me in the right direction!

Using Windows 7. These were suggested. Of course none of them made the slightest difference.

   media.autoplay.default = 5 [0:allow;1:blockAudible;2:Prompt;5:blockAll]
   media.autoplay.blocking_policy = 2
   media.autoplay.allow-extension-background-pages = false
   media.autoplay.block-event.enabled = true 

Does anyone on here understand this stupid video "follow us and block the page for stupid reasons" thing? How can software designers be so brain dead and out of touch with the rest of the planet? I do wonder sometimes.

Hi Everyone, My Bank has suddenly decided that ALL cookies must be allowed before letting their customers in -- a requirement with which I wholly disagree. My FireFox is set to block anything that moves, and supported by Ad Blockers and Ublock too. Is there a way in which I can configure FF to allow me into the Bank site without having to change my "secure" settings every time? I am no computer genius - so please make it simple for me.

Thanks everyone.

I see no way of doing this. You'd think there would be an ADD option somewhere in the search engine page. Instead it takes me to the Add-Ons page. https://addons.mozilla.org/en-CA/firefox/extensions/category/search-tools/ What has this got to do with adding a search engine to the browser? Must be a mistake.

It appears web sites can track my activity on their site. How do I make it so a given web site can't track me? Does Firefox have a setting that makes it more difficult to track me on a given web site? I've seen where a VPN, not sure what that is, can be of big help. How do I initiate a VPN and are there free VPN's? When I visit this particular site it states, "from your site login activity" and goes on from there what they want to do. How do I make it more difficult for a web site to be able to track my log in activity? Will a VPN solve this problem? Or, does Firefox have various accessories that can do the same thing? I know deleting cookies with this particular site does not solve the issue for me. Can someone help? Thank you.

Hello, I am using firefox 83.0 and I don't want to update it (Why? Because I've an old PC with poor hardware and the playback of online videos is lagging/shuttering in releases after 83.0)

BUT firefox 83.0 doesn't support private fields which make some webpages unable to be loaded. the private fields was supported starting in release 90.0 and I'm using 83.0

So, I need a way to make firefox 83.0 support private fields, Is that possible? Is there a certain files should I edited or replaced to make it support private fields?

Any ideas would be appreciated.

I have been having constant problems with my email. Not sure if it is a Microsoft issue or Forefox? But, the problem is when I reply to a email in print, I keep getting blue lines when I try and type in my replies. The blue occur when I try and correct a problem with my typing out a reply. If I have to correct or backtrack a word or sentence, the blue line appear. Very frustrating I have to try and remove the blue lines before I can proceed. Can someone please help. Thank you.

I tryed Firefox 115.8.0esr and 115.9.0esr 32Bit on Windows 7. (78.15.0 works) Firefox crashes(the whole program, i mean no tab) on "about:support" or some pages on support.mozilla.org like https://support.mozilla.org/de/kb/firefox-leistungseinstellungen always reproduceable.

I disabled all Addons, i disabled this power optimizion setting, removed usercrome.css same. With Firefox savemode it dont crash. Spyware is blocked, means datareporting/telemetry/ping by disabling the options and empty the urls (like on FF 78 but it dont crash). Somewhere i read firefox can crash on a empty url, but i assume its fixed long time ago. A wrong, unreachable or empty url should not crash on well programming. Think about countrys that blocks urls, adblocker, pihole and so on. I dont remember about what url i read.

Does the savemode revert all about:config settings? What does support.mozilla ask the browser that causes the crash? It know it seems to identify the Browser, but usual its done by useragent and no "internal" communication.

Then FF always crash on ebay.de search if you scroll or change settings while the page is not ready. Spyware is too blocked by Hardware, ebay may wait for some ad? But thats already on FF78 but on 115 it seems more often, this was not with FF 52. But some sites including ebay stops to work with FF52/78 so no choice.

Can't login to usaa.com banking site. keeps refreshing login page Using FF desktop latest ver. / win 7

I enter/submit my USAA username on the login page via a username dialog box. I then expect the password dialog box to open, but when I submit the username, FF flashes, i.e. the password dialog box displays for a split second and reverts right back to the username dialog box.

This happens at usaa.com with my user agent set to Windows/FF v 113. BUT if I set the user agent to Android/phone FF v 113, USAA detects the browser as Android/phone FF and it redirects to user agent to https://mobile.usaa.com where I AM able to enter username/password and login.

So what is wrong with FF? There are multiple threads of users unable to login to banking and other sites on the FF browser.

I have had no trouble using Firefox for many years and am able to access all/any websites excepting for one which upto a few months ago I had no trouble with. The one that I am unable to access is

  https://www.scc-online.org 

and all I get is the "The connection has timed out.." comment on an otherwise blank screen. I have contacted the webmaster who says that I am the only one with this problem. My neighbour who uses MS Edge has no trouble in displaying the website. He uses the same ISP as I do but uses Windows 11.

The webmaster says that it might be that I am using Windows 7 64bit and that Firefox cannot handle this particular website. Alternatively he suggested that my ISP was the cause of the problem although I have been using the current ISP for over 20 years and have never had this type of problem.

I have three computers all with Windows 7 and Firefox and they all have the same problem.

Is there any help available for me as the information on the "website" is important and I do not wish to have to go to my neighbour to view the website?
