Firefox Support Forum

Hello,

This morning I tried opening FireFox and it would fail to open. Tried everything said on the "Firefox won't start" on the find solutions page and many youtube videos using command prompt inputs. I cannot open in safe mode and neither can I make a new profile using -ProfileManager (won't open) what happens is Firefox appears to open for just a split second some sort of error message but its impossible to see what it is. Also tried disabling security programs have ran many scans on my computer for spyware, viruses, etc but nothing. Could this possibly have occurred because I left a couple tabs open overnight??? Also to add it is not running in task manager when I try to open it. If anybody else has a fix or the same issue please let me know. Thank you.

Firefox keeps crashing, when I boot it up a prompt appears for half a second asking if I'd like to go to safe mode, but the prompt window instantly closes after half a second. I have tried refreshing the app, uninstalling, and reinstalling, and nothing seems to work. The app was working a day before this. How can I get it to work properly again? It is worth noting that I had to ask my parents to allow my computer to use firefox the day before all this happened, but after that, it worked fine. Only now there are crashes every time.

Whenever I go onto one specific website to listen to music, everything works fine but for some reason, when I open the same website in Private Browsing Mode to avoid getting clapped by the algorithm, it always automatically sets the volume to around 50%. I can easily get around this by just dragging the volume bar up but it has been months and it's starting to get a bit annoying.

I've tried clearing the cache, changing the default volume in about:config, disabling all extensions, clearing cookies & site data, resetting my preferences, refreshing Firefox, uninstalling Firefox, following a guide to clear Firefox's residual files, and clearing all of my computer's temporary files, but it still defaults to 50% volume in Private Browsing Mode

Any help at all would be greatly appreciated

When loading certain websites, the images load correctly, but the text is scrambled (see attached image). About 1/3 of the sites I visited today were scrambled, others loaded fine. This just started to happen last week. I tried downloading and installing a new copy of Firefox but it did not fix the problem. I cleared the cache but no luck. This is on an iMac operating on IOS 10.9.5. Any suggestions on how to resolve this issue?

Recently I figured up that Firefox 90.0.2 (64-bit) doesn't open my website (https://e-expo.online/) It's very strange, because Google Chrome, Brave, Opera, Vivaldi and Safari opens it perfectly.

But every time I try to reach my site Firefox shows me this: " Secure Connection Failed An error occurred during a connection to e-expo.online. The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem. " I didn't find any advice at the Internet of how to solve it. Can you help me?

I want to clear the Firefox browser history and cookies on my Windows 7 Home Premium computer. I am instructed to click the tools Icon then click History then select "Clear Recent History" for another menu. However I am unable to select "Clear Recent History" it is in light Grey and cannot be highlighted to be selected. What am I doing wrong? How do I clean up my browser history can remove any stored cookies?

I need to know how to disable a blocker? I am on a Verizon website page and trying to post a review, I get message to "disable ad blocker" before posting my review.

When version 89.2 rolled out, I was highly displeased by the fact that the default theme now no longer properly reflected the Windows theme settings (extremely noticeable on my end, since I use the Windows Classic theme with customized "3D object" colors); this defect had already affected the options dropdown but had now spread to the address/navigation bar, bookmarks toolbar, and scrollbar. This was extremely annoying, especially since none of the add-on themes can properly duplicate that aesthetic function. One of the things I liked about Firefox was that unlike Chrome, Opera, and Edge... it actually still respected the Windows theme settings (which programs like browsers should do by default). And now, that prized trait had been inexplicably and insensibly discarded.

I was further displeased by the removal of the dividing lines between tabs. This made Firefox substantially harder for me to use, almost headache-inducingly so. Whoever you have testing these changes before rollout - if anyone - should be replaced, because this was a massive accessibility downgrade. Unacceptably so.

These changes were so frustrating and ugly, and made the browser so much more difficult for me to use, that I reverted to version 88 and continue to remain on that version.

Does version 90 resolve these issues? If it does, I'll update. But if not.... then in my opinion it should be axed and you should cease pushing it in favor of working on a new version that does fix these poor decisions. And I'll be sticking to version 88 until that happens.

I want to get rid of adblock which I installed as an add on.

It doesnt work very well for my browsing needs and is continually getting in the way with selling pleas.

So how to get rid of it ? I do see that I can get a list in firefox of installed add-ins, so why cant I click on a delete delete button alongside the add-ins that I don't want ?

I just updated to 90.

Suddenly all my tabs no longer show the delete cross. There is a 1 pixel spot that's hard to see.

When I troubleshoot and restart with addons, themes, etc. turned off, they are back. When I try to test each addon, I get no results. All I can think of is the themes are screwing up. I've tried different themes with no results. Can I turn themes off to test this issue?

Any other ideas?

Ever since version 90.0.1, now using 90.0.2, the mouse has become very sluggish/jerky, even in settings pages. I have no extensions or addons installed and am using the system theme. Troubleshoot mode works fine and refreshing firefox does not help. This is on Windows 7 Ultimate.

Thanks, Steve

I have minimal add-ons (adblock, multi-acc containers) and don't know why useragent always sets to Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0 after browser restart.

Since a couple of weeks my Firefox browser for Windows 10 64bit has issues. Last update 90.0.2 did not work either,and the issues is still there. Internet is extremly slow,some sites will not open and i cant logg in to Facebook. This site opens every other time. The internet connection is stable.

When we open Mozilla Firefox for 1st time, it asks for Master (Primary Password).

Once we enter the correct password, then it accepts it.

After couple of minutes or 1 hour later, it prompts again and again.

Very inconvenient to keep entering the password again & again if it is already entered once & window has not been closed.

Seems like a bug, please resolve it.

I am really tired of FF notifying me that an update is available. Every few minutes for the entire session. I know when I want or if I want to upgrade. Let me decide. Let me disable the notifications.

Is there a way to turn of update noticications once and for all? Thanks

I am using Firefox since several years with a PrimaryPassword for saved passwords. With Windows 10 it is used since a year or so. I regularily kept Firefox open for several days, but had no issue with it. But since some weeks firefox is asking for the Primary Password every day. This is quite anoying. After entering the password again, it continues to work, but will ask for the password on the next day again. Another post talks about a possible issue with some specific virus scanners, but I am just using Microsoft Defender Antivirus, which ships with Windows 10. I did not add any Add-on recently, so I suppose an issue with one of the latest Firefox updates (current version is 90.0.2 64-bit on Windows 10). Thanks for any tips.

After the last update to version 90.0, I can't continue to use firefox browser. The problem is about opening google sites (youtube, gmail). Other websites seems to work normal, but I can't open youtube and gmail now (google.com itself works heavily). When I type url and click enter, it takes so much time to load, often not loading the site or partially load. Other browsers installed on the same system works normally with the "problematic" websites. I tried hard reload (ctrl+f5), cleaning all browser data, and uninstalling and reinstalling. None of the mentioned actions helped. Please help me to identify and solve the issue.
