Firefox Community Forum

I am using Firefox with the uBlock Origin and Cookie AutoDelete extensions enabled. When I try and load Gmail or any other Google site, I get a blank page and nothing loads at all. This only occurs when my VPN is on (I use Private Internet Access). However, even with the VPN on, Chrome will still load those sites. Disabling the VPN means that the sites load normally.

My guess is it might be some sort of privacy setting in Firefox, but I don't understand what it could be. The only thing that breaks/fixes the sites is connecting and disconnecting the VPN, irrespective of which country I try and connect from.

let's keep it as brief as possible.. i have no idea what the hell the degraders of cloudflare are doing, for the past YEARS all sites that required cloudflare worked just fine, and now i lost access to multiple sites on firefox because of the cursed "are you human: captcha loop" i'm looking for extensions, i'm seeking github codes that i don't even know how to execute. the loop keeps demanding me to change the browser to a chromium.. isn't this supposed to be treated as a targeted cyber crime? from google against mozilla? how do i fix the captcha endless loop?

This was one of our primary suppliers for technology. Contacted them they just said "suck it up, princess".

Recently AWS started doing "human verification" on all VPN traffic to websites they host on their CDN(s). This results in all our Windows 10 PCs running Firefox ESR 102.13.0 going into an endless "Human verification" loop, never able to access the website.

On the Windows 2012 R2 server we have access to the above website works. We see "human verification" for a second or two and then the website is displayed.

So, copied my profile from a Windows 10 PC that doesn't work to the server and it works.

I've tried with tracking protection off. Turned off all adblockers, run in safe mode with all addons disabled, cleared my cache, deleted all cookies Created a new profile and still no go. Turned off Windows firewall, moved hosts file out of the way. Still no go. Also deleted prefs.js to run firefox as completely vanilla without any changed preferences.

I'm not inclined to install malware, so chrome based browsers are not an option. They are actually blocked so I couldn't install them even if I wanted to.

All PCs are on 21H2 3208. Upgrading is not an option at this time. PCs will be upgraded mid-late 2024.

All PCs are required to be connected to VPN at all times as we work from home. Being on call late into the night also means we can't just disconnect. We use NordVPN. Yes I know there is a lot of paranoia about VPNs being the source of all online crime. I just think that's an over-generalization. A convenient excuse.

https://www.scorptec.com.au did a similar thing earlier this year, but at least with them we get a captcha and can get to their site.

Could this be a browser issue, or is this more likely to be a Windows 10 issue? Also updated Windows 10 to latest patch each month and it's been the same for three months.

On version 89 while on Google Images, I can no longer click the image thumbnail to bring up the side menu on the right with the full size image.

It previously worked fine. I tried troubleshoot mode with all extensions removed and same issue. I tried on chrome/edge and later versions of firefox above 100 and it works as well.

My guess is there was some recent change on googles end that broke this on the older version. 89 supports webp so im not sure its that.

I like this version and would like to exhaust all possible fixes before defaulting to updating.

Hi, I've got a Wordpress website which contains some clickable links that run Javascript code. I have used obfuscation to protect the Javascript code and lock it to my domain. It all works fine for Microsof Edge and Google Chrome, but fails to display for Firefox. Is it normal for Firefox to not display obfuscated code for user protection or something like that?

Since this week I have been unable to access flightradar24 web site due to a problem with WebGL. It tells me that I need a compatible browser e.g. Firefox

I am running Linux Mint 21.3 Cinnamon on and I7 processor with a NVIDIA Corporation GK208B [GeForce GT 710] graphics card.

I have edited the about:config file as follows:

webgl.force_enabled TRUE

but noted a collection of failed messages as shown on the attached screen shot.

This web site is still accessible using chromium on the same computer, suggesting that there isn't a hardware problem.

Thanks

Video on some websites is choppy after updating to a newer version of Firefox (115.8.0esr). I have attempted to upload a video of the problem but it seems only still images are allowed and this doesn't illustrate the problem. An example website where this occurs is https://www.fiat.it but there are plenty of other examples. It looks as if the playback is jumping forwards and backwards between frames. Strangely Youtube videos seem OK.

Some information which may be of use

OS: OpenSuse Leap 15.5 HW: Dell Precision 7510 with Nvidia Quadro M2000M video card and driver version 550.54.14

I have also noticed that when starting Firefox from the command line I see frequent messages like

Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index2/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/cpu0/cache/index3/size Sandbox: attempt to open unexpected file /sys/devices/system/cpu/present Sandbox: attempt to open unexpected file /sys/devices/system/cpu Sandbox: unexpected multiple open of file /proc/cpuinfo

Probably not relevant but I included it just in case it is useful

Any help you can offer with debugging would be much appreciated, thanks

Starting yesterday, every youtube video I try to watch never plays or is in a constant state of buffering. It works fine in Edge, and Twitch streaming has no issues so its definitely not my internet connection.

I've already tried clearing my cache, rebooting, clearing it again and refreshing Firefox and the issue remains. Disabled adblocker as well. I am currently on version 106.0.5

I have been dealing with problems with Firefox and YouTube for a long time. Every time I open a YouTube video in a new tab it would always give me this grey screen that goes away after a long time waiting.

I have tried:

• Refreshing Firefox
• Reinstalling Firefox
• Troubleshoot Mode, which the problem persist in troubleshoot mode so its not an addon
• Tried creating a new profile
• User-Agent Switcher which doesn't work all the time.

I want to avoid going chromium-based browsers but this is making me consider.

This morning I could not log into the Schwab customer website using current Firefox version 123.0 on Windows 11. Reverting to version 122.0b9 solved the problem. Before the reversion I tried clearing cache, history, passwords, etc, and I tried a full reinstall of version 123.0. What else would prevent a connection to Schwab when other websites worked fine?

Whenever I try to sign into any Google site whether it is Gmail, Google, Youtube. or even signing into a site with a google account like Pinterest I get sent to the google help page taking about clearing cache & cookies. Even from there when i click sign in it just refreshes the page never actually taking me to the sign in page.

Just in the last few weeks, "buttons" on web sites do not work in Firefox, but work fine in Chrome. Example: https://www.mealtrain.com/users/sign_in/ The sign-in button does nothing in Firefox, yet works fine in Chrome. V. 125.0.3, Windows 10.

My Environment: Host Machine - Intel Core i7-4771 @3.50GHz, 16GB RAM NVIDIA GeForce 210 Display Adapter, Intel Gigabit Network Connection (ISP connection is around 700MBps).

OS - Windows 7 Pro V.22H2 Browser = Firefox ver.128.0.3 64bit.

Virtual Machine (VM) - Oracle Virtual Box Ver. 7.0.20 r163906, RAM = 4GB, Network = Bridged Adapter.

OS = Windows 7 Pro V. 22H2 Browser = Firefox ver. 128.0.3 64bit.

The Problem (In my VM only because I never browse sites on my Host PC): Toronto Sun website "Sign In" Screen never loads. A quarter circle just goes round and round. The website in question is - https://torontosun.com/sign-in/ The website itself does load fine and I can browse the site and all articles. But I cannot log into the site because the "Sign in" screen never loads. Also, Firefox tabs crash very frequently on this whole website.

Firefox is the only browser that I have on both my Host and VM (I have deleted MS Edge since it cannot be uninstalled).

On my VM, I tried installing Google Chrome and it works fine. The Toronto Sun Sign In page loads fine and I can log in.

On my Host PC, Firefox actually works. I tried it to see if the "Sign In" screen appears and it does and I can log in. It is only on my VM that it does not load.

What has Changed:

The Oracle Virtual Box software was just updated from ver. VirtualBox-7.0.18-162988-Win to ver. VirtualBox-7.0.20-163906-Win.

What I have tried: I have already done the following: Cleared - "Everything" including History, cookies, Temporary Cached files and pages and Site Settings.

I do not have any add-ons or themes installed.

I have cleared all Windows and User Temp Folders and files. I have rebooted several times in the past couple of days.

I tried increasing the VM RAM from 4GB to 6GB - did not help.

I would appreciate a solution.

Thanks very much. Kenneth

On certain websites I am getting scrambled text, mostly in headings and titles, not so much in body text. I have followed several tips from other posts like mine, i.e., installed Open Sans font, but that did not do it. I turned off hardware acceleration, and cleared the cache. The only thing that did work was to start Firefox in troubleshooting mode. I only have two add-ons running, Short URL and Dashlane, I doubt they're responsible for this. Any other ideas?

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

This problem exists ONLY on Firefox. I vary search engines, from DuckDuckGo to Presearch and Startpage depending on the search results I get.

For no apparent reason I will get a "suspended connection" message on Startpage while using the Firefox browser. I have included both the link and a screenshot of the problematic page. The page will open perfectly several times, and then suddenly, in the same session, if I open a new Startpage tab, this message will appear. While the suspended connection message is visible in Firefox / Startpage, I will try Startpage in Edge, Opera, Chrome and Midori, and they all open to the Starpage beautifully.

I am using the Firefox 125.0.3 browser, I have cleared caches and cookies, and run full malware scans, with zero negative results, and yet this problem persists. It is sporadic, and does not occur on a predictable basis. It occurs whether the Mozilla VPN is on or not, and switching from on to off or off to on changes nothing, even after refreshing the page.

I am assuming that this is a Firefox issue, as the problem does not occur on other browsers

I can easily switch browsers and / or search engines, but Firefox in conjuction with Startpage is my preferred combo. I just find it frustrating in that I cannot fix it myself.

So....Ehhhh...what's up doc?

After updating the Mozilla browser, two sites related to watching TV movies stopped opening - Apple TV and Canal +. The Apple TV site does not respond at all, Canal + shows an error. Clearing cookies doesn't help. Another browser, Chrome, opens pages normally.

Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.
