Firefox Support Forum

Ever since I started using Firefox I've found that if I Google a subject and then try to open a resulting listesd website which is marked as an "Ad", it won't open and I get a "Server Not Found" message. I like Firefox a lot but this is plain irritating!

On the Help pages I found a suggestion about changing the proxy setting to "No Proxy" (I'm just an individual at home, running through a standard BT hub), but that doesn't seem to have made any difference.

Any suggestions would be gratefully received!

Thank you for taking the time to read this Have a nice day

Hi,

From two to three weeks ago, every time I open windows, my firefox browser reboots twice. It does not give any error message and when it reboots it goes back to home page. I removed all extensions, then I updated the browser and the Graphic Card, in vain!

Any help please

When I use shortcut control + Tab with Firefox 79.0 (64-bit) (MacOS Catalina Version 10.15.6 (19G73)) i to often see blank page miniatures but not real page thumbnails. Looks like Firefox made page snapshots not so often or correct.

After update to 79.0 version, (on Win 7), the cursor totally disappear, an so it's really unconfotable to identify what I'm doing... Now it's possible to identify the cursor position only selecting some caracter, using mouse or case key + arrow. I tried to find some question on the web, and founded to set something in the "about:config" system, but in my list, for example, don't appear the "ui.caretWidth" row. I saw this problem appeared in 2017 too. (It appear NOW, for me...) I don't think to be the last person to use win 7... Can someone helps me?

Not every time I can reproduce this bug, but when it happens after resuming from suspend, the firefox is crashed with the small window to report a bug to mozilla or if the window is still open, some tabs crashes at loading the page.

Whe I try to open from shell and crash happens: ExceptionHandler::GenerateDump cloned child 9750 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal...

I am having problems while trying to watch YouTube with the Firefox browser. I keep getting as yellow bar at the top of the page when trying to do anything on YouTube. A screenshot of the error is attached. I've asked Mozilla about this before, and I am also trying to get a fix from Dashlane. It concerns the message "a script in the extension Dashlane is causing Firefox to slow down" then it shows Learn more. When I open that if the warning stays long enough to click on it. It recommends changing dom.max_script_run_time. It shows it is set at 10, and will not allow any change as suggested. Then it suggests adding JavaScript toggle on and off. That does not help either. I would thank anybody between Mozilla and Dashlane that can provide a reason for this continued error message and how to fix it. This has been going on for months.

im running win10 version 2004 on HP Specter360, 64 bit, Intel I7 8th gen. Since I installed Firefox 79 and a new Eero mesh router, TLS handshake is extremely slow and makes Firefox unusable. Often get time out errors.Any thoughts?

When I use Firefox 78 all requests are allowed. When I use FF 79, some (few) requests are blocked. Those requests break the page from loading properly. There are no messages in the console that suggest anything is being blocked. And the network tab just shows "blocked" on the request with no indication why it was blocked. I have not requested those URLs be blocked and the context menu has no "Unblock" option. Other requests that were slightly before and very similar looking were not blocked, some that come after and look similar are not blocked.

I have disabled all blocking features in Security & Privacy. Still blocked. (I don't think it was S&P blocking, there are no warnings etc.)

Otherwise, this an "out of the box" install with no changes made. Myself and a colleague are having the same problem with the same URLs being blocked. Other browsers, and earlier versions of FF are fine. Only FF 79 is experiencing the problem. I read the release notes, nothing stood out to me as a reason to block anything without an explanation.

(You won't be able to browse to our Jira, we 403 any requests from the internet. And these resources causing the problem are only needed after you login.)

Any suggestions on how to work out why those specific requests are blocked??

I mean, all web videos, include Youtube, Pornhub, Bilibili, etc, once I click the fullscreen button, it will crash in a short time. I have disabled flash already, it doesn't help.

Extended desktop, two different PCs, vertical layout.

Upon opening Firefox a white bar appears across the bottom of the top screen and the only way to get rid of it is to hit F11 (Fullscreen) twice. Minimizing, maximizing, restoring all have no effect - only taking it from a normal window to Fullscreen view (no menu bar or tabs), then back to a normal window works.

It happens on every new window opened and it doesn't matter which display it is opened on, the bar will be there if moved to the bottom screen, until F11 is pushed for that instance of Firefox twice.

This has happened before and it would seem to go away on later updates, but it is currently visible on every computer I have that has one display above another.

Ever since my Firefox updated on my windows 10 I have been having a lot of problems. Very slow loading times, any video I watch (whether it is youtube, twitch, hulu, etc.) buffers constantly, and if i have even only 2 tabs open i get the message in the yellow bar saying a webpage is slowing down your browser. I have tried a few different things; virus scan, checking installed programs to make sure nothing thats not suppose to be there is there, running firefox with add-ons disabled to see if that helps (didnt change anything), and restarting firefox. So asking for help on this, any solutions or insights are very appreciated. Thank you in advance.

Hello, whenever I use the right click, the pop-up menu triggers but it immediately registers a left click. This behavior is VERY annoying since it means that I accidentally go to the previous page whenever I right click.

So far it only happens when right clicking on the web page itself, and only on Firefox.

I've installed Arch Linux x86_64 with the 5.7.12 kernel and using i3-gaps as the WM

Please help I tried many times but my websites https://10hunts.com/ doesn't load in Mozilla firefox I'm tired now

I think my browser is preventing me from accessing notifications and scrolling on my Facebook group. I tried it in IE, and it works, so how can I fix this in Firefox?

Opening links from external applications (i.e.: Outlook, Word, a PDF, etc.) begins to open a new tab in Firefox, sometimes it'll open a "full" tab-width before hanging, more often than not, I'll see a sliver of the new tab while Firefox sorts itself out.

Typically when this happens, I'll see upwards of 50% CPU usage from Firefox itself. Memory seems sane.

Hardware acceleration, whether it's on or off, makes no difference. Issue persists in safe-mode, and safe-mode with add-ons disabled. Issue persists in Firefox and Firefox Developer Edition.
