Firefox Support Forum

Suddenly, when I search the web with a topic search term, e.g. "thrombin", I get the error message: 'The page you are looking for cannot be displayed because an invalid method (HTTP verb) is being used.' Can you help me resolve this problem?

When I try to log in to any Google "Ecosystem" (i.e Gmail, Youtube etc.) I see it (check screenshot below). I'll use Firefox Developer Edition. In vanilla Firefox and other browsers, everything works as usual.

When I open gmail in Firefox browser, I lose the connection very often, it also happens with google drive. But it does not happen to me if I use Outlook from the web, I only lose the connection with Google from Firefox.

However, if I open the same thing using Google Chrome, this does not happen, it works correctly throughout the day, and I do not lose the connection.

My version of Firefox is 100.0.2 (64-bit) on my notebook I have Windows 10 Pro installed.

Clicking on the spacebar, does not produce a space between words, when typing text. I'm using a Mac Mini M1, on macOS Monterey (V 12.4), along with a Logitech MX Keys for Mac keyboard.

This happens randomly, for instance, on this very message. I previously posted a question regarding another problem that I came across with the same hardware and Firefox.

I found the solution to that problem by disabling an Extension in Firefox, however, I can't begin to think where to look for what setting, that may be causing my current problem.

Below is the crash report:

Hello, I'm using Firefox 100.0.2 (OS: Ubuntu 20.04). It is not possible to manage if/when firefox updates are installed. In the options-section, there are some information about the current version number, however no chance to configure anything update-related. Updates just happens automatically and interrupt current sessions, leading to spontaneous (and surprising) dysfunction of the opened browser. That's very annoying in case of video conferencing, for example, because it is not possible to open any new tab or windows, always the note there "you have to restart firefox now" - in practice, just like a crashing error. And, the suggested restart does not re-open the current opened tabs/URLs!

Furthermore, within some updates, my language settings get lost, so it turns to English language automatically and I always must add my language packet manually again and again. Thats really annoying and maybe completely disruptive for people that are not able to read in English!

Is there any chance to come over this? Otherwise I guess I must leave using firefox as browser, however this would be not the aim I actually follow. Thx!

When I open a website, the message "Firefox is already running" comes up every time. Task manager says nothing is currently running. I have to click "close Firefox every time I go to a website. Can you help? Thanks Alan Murray

I can play videos and audios on another browser or files stored on my computer, but just now I cannot on Firefox. I saw the FAQ explanation about Windows 7, but I have been using Firefox for years including just hours ago using Windows 7. Why would this happen right now? Did some new version just get installed? If so, can I return to the prior version and turn off the automatic update?

Thanks, Phil

My problem is this:

If I click on the open new tab button, and then I keep my cursor there, such that I get the little tooltip "Open a new tab (Ctrl+T)..." , Firefox will stop the address bar from updating---it won't show my keyboard inputs, not will it search, or do anything else. This will resolve itself after I move my cursor away from the open new tab button and the tooltip stops showing, even my inputs will appear there.

This quite annoying, especially when opening a tab to search for something quickly...

Hello

I have just updated firefox 103.0 64bits on my pc windows 10. And bigs bugs : all web pages became huge zoomed at around 150 - 160% !

I managed to fix the huge zoom problem by installing this firefox extension : https://addons.mozilla.org/fr/firefox/addon/zoom-page-we/?utm_content=addons-manager-reviews-link&utm_medium=firefox-browser&utm_source=firefox-browser

and setting all web pages to 90% zoom with it. But this is not a solution because firefox has to fix this bug since this update! :(

And the toolbar has become much higher, which decreases my screen height, it was better before! :( See my screenshot where i circled in red the height of the toolbar which has become higher! :(

even the tab bar has become higher! :( i managed to reduce it a little in height thanks to a code that i inserted in the file userChrome.css ,but the result is not beautiful : the texts are too flush with the line ( see my screenshot where i circled in blue the tab bar that i reduced with code in userChrome.css )

Firefox version: 102.0 (64-bit) System: Windows 10 21H2

I recently downloaded a file that may have had some sort of virus or malware. The file came up negative in Windows Defender and Malwarebytes but I deleted it anyways; however, I still get a download popup every time I open Firefox telling me that "This file contains a virus or malware." I've cleared the download library and browser history (cookies, cache, etc.) but I still get the popup from the Firefox.

Is there any known fix for this? Thanks!

My picture-in-picture remains in full screen, even if I double click with my mouse. When I click the ESC button it just closes completely. I have restarted both Firefox and my computer, but I keep getting the same problem. Not just in YouTube either, also on other websites.

Since the latest (5 May 2022) update to Firefox (to Firefox 100.0) my Gmail account does not work properly on my desktop running W11. Gmail frequently disconnects for varying periods, then reconnects, only to disconnect again almost immediately. Gmail will not let me open another account from within the current account. This does not happen on my Android phone where Gmail works properly. Neither does it happen when I run Gmail through Edge on my desktop. Hence I presume it results from an interaction between Firefox100.0 and Gmail. My wife has exactly the same problem using her Microsoft Surface Laptop under W10 since this latest update.

When playing music on music.youtube.com, if I navigate away from the tab, by either moving to a different tab or opening a different application the music pauses. This happens consistently with two different Firefox profiles.

I admittedly have a quite a few plugins installed, so I tested this in a private window and this issue does not occur.

I attempted disabling the obvious plugins UBlock, 'I don't care about cookies', and Tampermonkey without any success. I also tried using a different user-agent without any success.

Hi,

My partner has an issue with Google working within Firefox (FF). The problem started around 27 April 2022.

In short:

• • Both gMail and Google Drive keep saying “Ooops … the system encountered a problem (#2003) - Retrying in x s…” and “Not Connected”.
  • The above message may stop for a period and then gMail within FF fails to render its pages properly. Icons go missing. For example the check boxes to the left of the emails disappear while the remainder of the subject lines remains. Menu icons across the top of an open gMail document disappear (like Download, Report Spam and Delete icons ….). This seems to suggest a cache issue.
  • Search within FF using Google fails also. After entering search terms and pressing ENTER, nothing happens.

Note:

• The stand-alone Google Chrome environment works fine. So gMail, Google Docs, Sheets etc work OK in the stand-alone Google Chrome app.
• Duck Duck Go search works within the FF browser.
• I have noted that if I simply log into MY Google Account under Firefox on her PC the same problem occurs.
• If we log into my PC the problem is not apparent using either of our Google Accounts. So it appears to be an issue on her PC.

I have tried :

• Flushing the cache in FF for all time, including data. Then rebooted.
• We have followed your procedures under “Help” ie Runs a Firefox a tune up; used “Diagnose issues” and “cleared the startup cache”.
• Have run Sophos AND MalwareBytes across the whole laptop. No PUPs or malware detected.

I uninstalled FF using Revo Uninstaller which initially uses the standard FF uninstall exe then it scans the drive for removes all FF files and entries within the Registry; then I re-installed the latest version of FF. Rebooted. No luck here either. I assume there is some remnant file that remains on the hard disk as some settings are retained after a new install.

Hardware: Lenovo ThinkPad , model 20QFS00B00. OS: Windows 10 Pro, vers 10.0.19044 Build 19044, 64 bit Firefox browser: is up-to-date; vers 99.0.1 (64 bit)

I can't find any recent issues related to this specific problem. Please advise what to try next.

Of course I'm happy to provide additional info if required or work through different scenarios to isolate the issue(s).

Thanks in advance for any assistance, Steve Gee

After i just updated Firefox to newest version .. I can not load any website anymore!!!!!! please make it so i can return to the previous version ASAP so everything works again.

Al those other solutions you guys give like clear cache disable en able etc don't work and take hrs of time

When oyu push a other update through some 1's throat atleast make it that it A)works B) option to roll back . TY

I am experiencing problems when using Duolingo, which is highly interactive.

This same problem was highlighted in Version 95.0.2 from a Windows user. The waveforms on System Monitor/ Resources are the same.

I am using Fedora and have 16GB ram. Have just ordered another 16GB ram, but think this problem is so severe that no amount of ram will fix it.

It periodically blinks and that breaks buttons that open menus and closes context menus from Firefox. Also disables some keys, the tested list is arrows, might need to test that on all. As it's version-independent, it might be a dependency issue. It also happens in safe mode, which is saddening.

I got mad at a website that wouldn't let me right click menu to save pictures, so I stubbornly saved them via less efficient means, in the process I picked up the Long Screenshot extension and this had an error shortly before or after I had an issue with Lightshot not appearing, other extensions did not appear either when I added them during this time period, but now these all appear with the exception of Lightshot, which gets deleted and reinstalled only to not appear, that of course being the problem, though I will also say that a right click menu not being there is like reaching onto my computer and pulling my finger away, sites that do that should be given the cold shoulder somehow, at least.
