Firefox Support Forum

In the past week I have found that I am now unable to log into some websites, can no longer download pdfs from websites, or word docs from email. I have had issues trying to access chat functionality with my web hosting company. This has forced me to have to start using Chrome is many cases.

Firefox is my favorite browser and I want to continue using it, but if I am unable to access the websites I need to, when I need to then I will have to eventually jump ship.

Is this happening because of recent browser updates? From search from past issues people have had I've seen firewall settings a possibility, so could it be my firewall? Or are websites just not trying to support Firefox anymore?

Any information would be greatly appreciated.

Several login pages don't load correctly, completely or at all since the last update. Binance homepage doesn't load the login menu (see attachment), direct url page just shows white screen. I also had some issues with logins on my health insurance site, downloading pdf's, everything just being incredibly slow, pages getting stuck, no loading icons. I cleared my cache and cookies, and it seems the problems got worse. I'm running a VPN, turning it off didn't fix these problems. Everything works fine in Brave. I tried troubleshooting mode, but once that was started up I didn't know what to do.

Hello,

my firefox is blocking javascripts loaded by domain itself. But only for one domain (cls-med.de). I do not know which setting forced the problem. The Javascript is also blocket in firefox-debugging-mode. Other intances of firefox do not block the javascript. can you help me please?

I know you cant help with part of it. When i launch a video i have bought on steam it now opens it on my default browser which is firefox, but it tells me its not up to date so i cant watch anything. at this point its forcing me to go back to chrome since it works.

Long term issue of losing pinned tabs because I break a tab off the main firefox instance to work on it in a seperate window and then at some stage I close the firefox window that contains the pinned tabs AND AFTER I close the breakout tab and this seems to remember that no pinned tabs ever existed. This behaviour is idiotic and clearly buggy, certainly shouldn't be a feature or normal behaviour.

The pinned tabs feature is advertised as placing permanently some tabs that open for sure at every launch of firefox in a known location to the left - things we use just about everyday (gmail, iCloud, reddit etc), hence their permanence and it seems to be impossible to code something that if NO firefox window is opened then when we launch Firefox we get the default view of our pinned tabs and a fresh page OR default homepage etc.

Seems ridiculous to me. Whats the logic here ? I vote FOR making this a permanent feature.

The window with 100 tabs of 6 months of research is gone. I clicked on a few email links, and now they show up in the history, but not the window I've been working on. Anyone know how to hopefully get the window back? Thank you

Firefox used to open maximised but now opens in a half size window. I recently had an issue, following a Firefox update, of Google maps controls in the lower right corner missing. Also I could not toggle between map views. After advice from the forum I changed the "privacy.resistFingerprinting from 'false' to 'true'. This solved the Google maps problem but seems to have introduced the issue of Firefox opening in a 'half size' window. Any thoughts on what to do next, or do I live with it? Thanks - Chris

I do not have any sound and all taps are unmuted. I have sound when using Google Chrome, Edge and when playing a video with VLC. I have tried to uninstall firefox and reinstall it, but still no sound.

Kindly help.

Newbie question: today I started out using Firefox, so bear with me.

I am trying to set the Firefox Home page to display a limited number of 'pins'. Did manage to get them there, but some other pins are automatically added (based on recent visits I suppose?) So I have 8 pins, 3 I don't want. When dismissing, I get other links instead.

Maybe this is by design and can not be changed.

Vainly search for a way to have only the few pins, that I want, show there, nothing else.

Thanks!

When I run the Divi Builder on the agencia221b.com site, it crashes firefox.

The testes I've made so far: If i run divi builder from other sites in the same hosting, it crashes firefox. If i run divi builder from those sites in incognito mode, everything runs normally. If i run divi builder from those sites in firefox troubleshooting mode, it crashes firefox. If i run divi builder from those sites with all extensions disabled, it crashes firefox. If i run divi builder from other sites in other hosting, all runs normally. If i run divi builder from those sites in chrome, in or out of incognito mode, everything runs normally.

This problem started some weeks ago with one site, after instaling a wordpress plugin. Now, other sites in the same hosting begin to have the same problem.

It only happens with firefox, always. It doenst happens with other browsers, never.

Please, can someone help?

Since the last update, my mouse is sticking for a second, from time to time. Whatever you did in that last update, I'm unable to use firefox. I have had to switch to google chrome until you fix whatever it is you broke.

Hello Firefox,

Thanks for reading my troubleshooting question. When using the Firefox browser (my favorite by far) I cannot upload low res (500x500 pixel) Jpeg photos onto my Squarespace website. I called Squarespace and they ran tests including uploading my photos successfully. Squarespace recommended I clear Firefox cache and history. Still no good. I then ran a Firefox refresh. No good. Finally I temporarily booted the God forsaken Microsft Edge browser and My Squarespace website worked just fine. Uploaded Jpeg files successfully.

I really dont want to be stuck with Microsoft Edge. Your help would be greatly appreciated.

Searching for Tickers you keep on getting the sandclock (it stalls) and loading charts crashes the site. Has been like this for ages. Please accept the challenge to make it work equally in Firefox as it does in Edge/Chrome.

in the last day firefox has all but stopped working on most websites. i can go to them and they start to load, but then they eventually break halfway through and either end up loading forever or produce an error. if i look at the console i see "Source map error: Error: NetworkError when attempting to fetch resource." this happens on twitter.com and raidbots.com to name two off the top of my head.

i did a complete refresh and even completely uninstalled and reinstalled the browser - it started working for a bit and then broke again. i have no plugins or extensions enabled currently (i have dashlane but this happens with it enabled or disabled). it's making the browser unusable. ive scanned my computer for malware and cant find anything either. i don't have this problem in any other browsers so not sure what else to try.

Tried this on a live site with a large image of name like something-welding-something.png

<IfModule mod_headers.c>

   <FilesMatch "welding">
       Header set Cache-Control "max-age=30, public"
   </FilesMatch>

</IfModule>

How do I prove it works? What am I doing wrong?

In Firefox enter yourdomainurl into the url box. Display webpage.

Open Firefox dev window go to network tab and filter by welding

On webpage hit <Ctrl-F5> network traffic shows image fetched from server.

Open another browser tab and look at about:cache?storage=disk Find the image and the expiry time is 30s past last modified time.

On webpage hit <Ctrl-R> network traffic shows cached. On webpage hit <Ctrl-R> nothing appears in network traffic!! On webpage hit <Ctrl-R> nothing appears in network traffic!! Wait, hit <Ctrl-R> again still But on the about:cache page the Last Modified time is now after the Expires time!

Enter some other domain (e.g. bbc.co.uk) into the url box instead of yourdomainurl.

Wait 30 seconds and then re-enter yourdomainurl (do not use back button). Network traffic for image shows cached. The expiry time now shows No expiration time.
