Hello,

Seems there is some difference between Firefox and other browsers.

If you want to overwritethe src of an image, you can use "content" from css. In my case this is used for customerspecific styling, being done via CSS only, while the default image is provided directly over src attribute inside html.

Greetings,

After a recent upgrade, i noticed that i can't browse to certain website using firefox, however if I used chrome or any other browser it i can.

after troubleshooting, noticed that in firepower (firewall I am using), the requests are using "ultrasurf client" image attached. Thus application gets blocked.

Made sure I don't have any "ultrasurf" plugin / addon installed, I even tested with running firefox in safemode but still same issue.

I also noticed that when I try to load a site, the connection doesn't go to that website IP but to one of cloudflare IPs. DOH is disabled, I and blocked all Cloudflare connections on the firewall.

Has anyone noticed this with their firefox ?

Version 86 DOH Disabled Firepower detects Ultrasurf client Connections are made to Cloudflare ips (Specifically to the range 104.16.0.0/12)

I couldn't find this so I worked it out myself... post this as a fix for others!

TROUBLE: I have had problems with scrolling down using the scroll bar on reddit and elsewhere. When it got near the bottom it would uncontrollably jump back up not allowing me to get to the bottom of the page whether I held it with the cursor or not.

FIX: Go into options, general, browsing and turn off SMOOTH SCROLLING and AUTO SCROLLING.

hi i see that i have a tab that uploads and i know its PID (via the task manager) I want to close him, but i don't know which tab it is, is it possible? Is there a way to suggest an option that shows the CPU and up/down usage when the mouse stays over a tab? or is there a soft or plugin to do that? thx

When my Microsoft Surface is in tablet mode and I click in any text field in Firefox, the on-screen keyboard pops up, there's a little shutter on the screen, and the keyboard closes. If I open the keyboard again by clicking in the task bar, the same thing happens again. The on-screen keyboard works perfectly in all other apps.

Anyone come across this before? Any thoughts?

I'm using the latest version of Firefox and Windows.

Hello! Our company has had this issue since May of 2020. out of 170 users, we will have 3 or 4 users per day crashing at random times. we cannot recreate the crashing on demand, its random times, random pcs. we are running the latest ESR version we do have a handful of PCs on the non ESR version also crashing. nothing in their extensions. we have tried running in safe mode and renaming the storage folder for some of the repeat users PCs but the crashing persists after a few days. we had all users refresh firefox but it will also happen again after a few days. we have tried setting a different home page for some users but they still get it. the only fix is to reinstall firefox and it will work fine for a few days but then will happen again. when they are in the crash cycle, nothing will get FF to open, only reinstall. FF is the default browser since some of our vendors require it. any help would be appreciated!

here are some of the users crash reports. I cant tell what is causing the crashes. we do have mcafee AV and have tested removing Endpoint security modules but still got crashing.

Firefox freezing - High CPU usage spikes

I don't remember exactly the date, but I think it started after a update(firefox/windows). The oldest pic I have is from 23/11/20. Firefox was running without no problems, then this started.

Gallery

The problem is High cpu usage from time to time. Making firefox slower and also freezing tabs. It's so annoying. Made me use Edge that runs incredibly smooth, I was impressed( I can even watch media in 1080p with no problem).

Then I noticed through the task manager that the 'Host service Windows font cache service' is always present, as you can see in the gallery. I didn't find anything related to that.

Tried starting in safe mode, refresh, uninstalled and installed today(24/02) and nothing worked. This is driving me crazy because I love using the browser.

My PC Setup is: Windows 10 Home i3-4130 8GB ram no video card

And I use the free avira antivirus.

I am using Firefox 85.0.2 (64-bit) on a Macbook running OS X 10.13.6.

This problem has been afflicting me for six months or so. On certain websites that open a new page in a new window, the new window instantly enters what I would describe as a "resizing loop": the window starts small and immediately maximizes. Each time it fills the screen, though, it immediately shrinks back down and starts again. This looping behavior continues endlessly, until I kill Firefox or somehow manage to get the malfunctioning window to close. On my employer's webmail, for instance, I'm not able to compose a new message, because it tries to open a new window and gets stuck.

The resizing is very fast and very incessant, fast enough to induce nausea in the unsuspecting user. Can anyone offer any suggestions?

Often when I do a search from the address bar, the search query is cut off at some point.

Say I want to search for "tofu quiche recipe", so I write "tofu quiche recipe" in the address bar and press Enter. This will often cause Firefox to search for "tofu quiche reci" or just "tofu qui". Even if the entered query, "tofu quiche recipe", is displayed in the address bar itself, it seems that the primary option in the drop down will have a certain delay in updating and say "tofu qui — Search with DuckDuckGo", and thus when Enter is pressed, Firefox will drop the last part of the query.

The issue doesn't happen when searching from the new tab page or directly from a search engine site, only from the address bar.

I installed Firefox on a MacBook Pro 13" (Mid 2012) with MacOS 10.15.7 Catalina. Before closing Firefox for the first time, I carefully opened settings and ticked "Restore previous session", under "Start" on the "General" settings page. But when I opened Firefox again, there were no tabs, just a "Welcome screen" as if it was the first time ever I use Firefox! This is extremely disappointing! I am really shocked! I had never thought that Firefox would screw me like this! I have been using Firefox on Windows and Ubuntu for many many years! I can add that it is Firefox 85.0.2. And now it updated itself to 86.0.
