Firefox supportforum

When I signed on to my computer this a.m. and clicked on the Firefox icon from my Task Bar (on the bottom of the page) to bring up my homepage, it wouldn't go. I rec'd a msg stating it "couldn't find" a .dll file or something. When I clicked on the icon on my desktop, it started a whole new page - I lost all my "saved" pages and my "favorites" menu was gone! What happened and how can I get my "normal" Firefox page ?

Hi

Some months ago I added a 32" samsung usb screen to my PC, my operating system is windows 7, This maybe coincidental and not at fault. Since adding the screen my Firefox browser crashes, what happens is the screen starts flashing and most of the display disapears you can click on some buttons if displayed or you know where they are but the only way to stop it is to close and reopen the browser, it seems to happen more frequently in a browsing session once its happend once, sometimes it dosn't happen. It seems to be triggered by the mouse scrolling wheel. I have removed and reloaded Firefox but still the same, when reloading it recognises the previous instalation and recalls some previous settings, I don't seem to be able to stop this happening. Lastly the fault does not occur on any other browser. Firefox is my default and prefered browser and I would like to cure this if possible, I have run virus scans etc and dont appear to have any contamination issues.

Any advise gratefully recieved

Many thanks Steve Hull

I am on Catalina OSX and when I press the maximize button (Alt + the green button, just so you know I am not making it full screen), or double click the top bar of firefox, it stretches the window all the way down resulting in the dock hiding a portion of it. This is the only app that has this behaviour and I tried looking around in firefox's settings to no avail :(

I can manually resize the window so it won't overlap with the dock but as soon as I quit and come back to it, it resets to the original problematic size.

Please help ! Pretty pretty pleeeease!

Thanks for your time and I hope every one of you is safe in these dire times!

I have had the following issue 5 times now over a longer period of time (Windows 10, Firefox 77.0.1 and earlier versions).

Rarely, when I want to start Firefox, I get stuck in an infinite loop. The mouse cursor changes to a "loading" cursor and starts flickering forever, trying to start Firefox. This is bad enough for my whole system to behave strangely, e.g. mouse clicks will randomly not register or release.

Upon inspecting the task manager, I find that `consent.exe` repeatedly pops up and disappears. I assume it crashes and then firefox tries to restart, repeating in an infinite loop ... I only recently found a dubious/hacky way to stop this without logging out or restarting my pc: When I forcefully rename `C:/Windows/System32/consent.exe` via console, e.g. to `.../consent.exe_`, Firefox will crash "properly" with an error message and I can rename it back.

I have no idea what this `consent.exe` does or why it is called, which makes finding the cause or fixing the issue very hard..

Details / attempted fixes

The most recent time I had this issue, it appeared after trying to open an external link while Firefox was open. Firefox then found a new update and started automatically updating to the newest version (77.0.1), before trying to open the link and giving an error message (I don't remember what it was..). To properly apply the update I closed Firefox, tried to open it again, and I started getting this infinite crash loop.

This is not the first time I had this exact same issue, but the cause seems to vary. The first time I encountered this was back when there was a buggy Windows update, which if I read my logs correctly seems to have been at the end of February 2020. As far as I can remember at this time, the issue appeared immediately after restarting my PC and updating Windows (no opening of external links involved). The only way I managed to fix it was by uninstalling that Windows update. I disabled the following updates for some months. At this time I assumed the cause was the buggy Windows update, but since then I had the same issue 4 more times. Of the times I can remember the issue appeared immediately after

• updating windows
•  ??
•  ??
• clicking an external link
• clicking an external link > automatic Firefox update > restart Firefox > crash

Every time I got this issue I tried many things to fix it, including

• restarting Firefox
• restarting the PC
• deleting my Firefox profiles in `%AppData%\Mozilla\Firefox\Profiles` and `%AppData%\..\Local\Mozilla\Firefox\Profiles`

none of the above worked any time I had this issue - nonetheless the issue would disappear randomly without me knowing what fixed it.

The first time when it was seemingly caused by the buggy Windows update, I even uninstalled and reinstalled all of Firefox, including deleting my Profiles in AppData. Even then, the issue persisted on a completely clean and barebone install of Firefox. However, since then it is seemingly caused by opening external links and the problem always randomly disappeared before I got to try a clean Firefox install.

The most recent time, the issue disappeared while I was trying `firefox.exe --version`, `firefox.exe --help` to find out my Firefox version (I don't know the correct commands, so nothing happened). This did not work, but when I then tried to start Firefox again, I got about 10 or so error messages on the first attempt (unfortunately, I don't remember the error message..), and then the issue was gone on the second attempt to restart Firefox.

One other random guess I have is that some of my about:config settings may be related, in particular I completely disabled any links from opening popups, be it a new tab or window. But this sounds really like a bug and I certainly do not want to undo this setting.

In the end I am not even sure if this is a Firefox or Windows issue, and I am also not sure what would be a better place to look for support. Should I submit the above as bug report?

I am also very reluctant to try to reproduce the issue since I have no idea what the fix is and spent hours on it every time.

Speedtest.net is giving me different results than Vivaldi or Edge. The download testing speeds are all over the place and choppy compared to the other browsers, and a tad slower overall result too. The upload speeds are fine. What does this mean?

I am running MACOS 10.15.5 on a MacBook Pro. Up until recently Firefox has worked perfectly. Now, and for maybe the past week or so, I get the pop-up error message "Firefox.app" can't be opened. No other indications or messages.

I have removed and reinstalled the app from the Firefox 77.0.1.dmg file. Still have the issue. I get the same msg when attempting to start Firefox in safe mode. I thought at first this issue may be due to the upgrade to 10.15.5 from 10.15.4, but a family member's Firefox works perfectly on 10.15.5. I actually don't remember when the jump to "5" from "4" actually happened. I have checked the forms and found nothing relating to this specific error. Perhaps I missed it.

I have attempted to recover Firefox from an earlier (6/2/2020)Time Machine backup which I believe was prior to the "5" upgrade, but the message is still the same.

Any help/suggestions would be appreciated. Thanks.

This happens in Facebook when I try to play a game: "The address wasn’t understood Firefox doesn’t know how to open this address, because one of the following protocols (fb-messenger) isn’t associated with any program or is not allowed in this context. You might need to install other software to open this address."

I am in Fedora 32 with Gnome and Wayland…when i want to change the properties of an bookmark in the sidebar, the context-menu doesn't work. Did anyone notice the problem or is there an bug report? (i do not know where i have to look at :/ )

I have the latest FF on my Windows desktop with no new add-ons. The past month or so when I load pages, usually ones that have a lot of ads, all the ads or other extras on the page start flickering - the icons for stop loading and reload alternate back and forth fast. I can stop the flickering by clicking on one of those icons but why does it do that? It makes the whole page distracting to read. I sometimes have to do that for page after page.

Hi there!

My firefox suddenly stopped to show me pages. I don't know what's the reason of it, however it doesn't work either in a safe mode (without any additionals) or without it. Also it doesn't work on 2 different windows accounts with different browser settings. I can't do anything there, and when I run the browser I can see the page content for about 2 secs, and then suddenly it crashes. When I refresh it again, I can still see the content for only a short while and it breaks again (image in attachment shows it). I'll be thankful for any help with that problem. I've suspected it's some kind of virus but anti-virus program doesn't detect anything.

Firefox 78 was installed last night. As of now I cannot get the address bar to work. When I type a URL and hit return nothing happens nor does clicking on the arrow do anything. Please let me know how to resolve this issue.

Hi,

Geolocation doesn't seem to work on Firefox for me. I can't use Google Maps or other location-based services even after giving permissions.

I found this post: https://support.mozilla.org/en-US/questions/1282004#answer-1297537

I got the following results:

https://browserleaks.com/geo - I get "POSITION_UNAVAILABLE" https://bestvpn.org/html5demos/geo/ - "failed" https://www.iplocation.net/find-ip-address - correctly gives New York, New York, the location of my VPN's proxy

I also copied the following from 'about:config':

Application Basics

Thanks in advance for your help!

If I start opening a hundreds-megabyte PDF, or a JS-heavy website, or a server just do not respond at all, I expect that when I'll press "Stop" button browser would... emm... stop: stop trying to render the rest of the page, stop trying to establish the connection... But notning happens. I don't see any reactions to Stop button. The only way to stop the download is to close the tab (I'm not sure, I hope it stops). By the way, it is especially "nice" when the program closes together with the closing of the last (as suddenly will be realized later) tab.

So, there is the "Stop/Reload" button. Does it do something like stop something? Or it is purely decorative/irritative? Or I just press it wrong way?

I had set the about:config settings after 75 came out to fix the address bar. Today I got 77.0.1 and now the address bar seems broken again. When I mouse over it, there is no longer a down arrow to click and show my common sites. If I click in the bar and then delete everything, the list of common sites appears. If I click away and click back into the blank address bar, now I have to hit the down arrow to get the list to appear. I need a way to get the down arrow back so the address bar works as expected.

These config options are all set to false:

   browser.urlbar.openViewOnFocus
   browser.urlbar.update1
   browser.urlbar.update1.interventions
   browser.urlbar.update1.searchTips
   browser.urlbar.update1.view.stripHttps

HI,

it's a problem that's been around for years, yet i never got an appropriate answer, so i'm asking here:

The longer i keep Firefox running, the slower my whole system gets and the slower firefox itself gets - up to a point (generally like about 10 hours or so) where everything becomes so slow, i have to manually shut down Firefox via the Task Manager. All that seems to be independent from the fact whether i actually do something in Firefox or not.

So i don't know what Firefox actually does while i'm away that kills my whole system, but i'd really like to know and i appreciate any help!!!

THX in advance
