Firefox Support Forum

I have used Firefox for many, many years and have always loved it. Recently, it stopped loading some websites. I have read and tried everything I have read and still can't fix the problem. I have to switch to Edge to load the sites. I am tearing my hair out trying to get this fixed, but I will have to use other browsers if this doesn't get cleared up. Some sites load and most don't, but there is no rhyme nor reason to what it loads and what it doesn't. I do not have a great deal of tech know-how and cannot seem to fix this according to my research. I get no "error" messages except that the page can't load. Please help. I would hate to have to learn another browser.

OS version : Windows 10 Pro 21H2 Browser version : Firefox Developer Edition 126.0 Beta 8 (20240501022718) Platform : windows, Web

EVERYTHING especially

 * The time to receive the first HTTP response when connecting
 * the time to call up the various css elements that make up the screen
 * the time to call up the img elements on the screen
is too slow.

tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.

I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

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!!

Greetings, Mozilla Community I'm reaching out to you to get assistance with an issue I'm having with Mozilla Firefox when trying to access the following website: https://strandsgamenyt.com/ I'm not sure if there's a bug in the website, if it's incompatible with some browsers, or if the browser is blocking anything, but it won't load.

Does anyone else have experience with this issue or suggestions for a solution? I've tried clearing my browser's cache and deleting extensions, but the problem persists.

I would appreciate any guidance or thoughts on making the website easier to use. I appreciate your help in advance.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.

Hello, Mozilla Community I'm contacting you to ask for help with a problem I'm having with Mozilla Firefox when attempting to visit the website https://canuckletoday.ca. The website won't load, and I'm not sure if that's because of a technical glitch, incompatibility with certain browsers, or anything the browser may be obstructing.

Has anyone else had this problem or has advice on how to fix it? I've tried removing extensions and cleaning the cache on my browser, but the issue still exists.

Any advice or tips on how to navigate the website more easily would be much valued. I'm grateful for your support in advance.

When I try to use needed tools on websites, Mozilla is blocking the page from opening. USPS will not allow me to track a package. When I enter the tracking number, the page just sits on white and the search just spins

Hi, I've been trying to get the Multi-Account Containers Add On to work on my computer for quite some time. Would be very handy for me. When I add the Add On to my browser the icon on the top right of the screen just won't show up. Don't know what I've been doing wrong...? How can I access the container settings someway else? I've made changes to my FF settings in regards to privacy via the recommendation from Sun Knudsen but don't really see an issue here. Thanks in advance!

macOS 10.15.7, Firefox 125.0.3

Unlike Safari, Firefox doesn't autofill passwords or 2-factor codes. Please implement these features or tell me how to get them to work. MacOS 14.4.1 Thank you, Steve

Firefox goes to eBay Portugal instead of eBay USA. In order to complete a specific task, I had to use Edge browser to get there. Why does it do that? How do I fix it?

I can no longer login to my webmail account using firefox, but I CAN login using MS Edge. I obtained a new ISP and set up a new email account. I was able to access the webmail account for about a month with Firefox. Then a few days a age, it just stopped: When entering valid credentials, the login page just refreshes (without errors) and doesn't continue to the webmail inbox any longer. So I thought I'd try a different browser and I used MS Edge. The valid credentials get me into the webmail inbox using Edge, but no longer works in Firefox. Any ideas what happened?

Google ReCaptcha is not working on literally all websites. Once I click on checkbox "I'm not a robot" It gets stuck on infinite loop. Although working on Mac OS in Firefox and Chrome or any other browsers. The issue is primarily with Windows version

I already tried clearing cookies, cache, disabling Tracking Protection, adding sites to DNS white list

Environment: OS Windows 11 Version 23H2, Firefox 125.0.3 For testing used: https://www.google.com/recaptcha/api2/demo

I get the message: Gmail may not work well with this browser version. Please upgrade to a supported browser. Just got it today. FireFox is version 125.0.3 for Windows 11. On gmail help, it said to disable extensions and add-ons. I did this, restarted Firefox and get the same message.

Where are all the tabs for the research I was working on? I stepped out of my office for a few minutes and returned to a very proud message declaring that Firefox had auto updated and now better than ever. Only all my tabs are gone. Why does every other browser save and restore tabs when updating, but not Firefox??? Do I have to go back to Safari or Chrome? This cannot happen!!!

Title,

The option to switch languages is also not present in the right click menu (see attached image)

I'm really unsure how to figure this out so any advice would be greatly appreciated.

Thank you for your time.

Headlines and other tabs are not showing text properly - Not even a different language - Example of the way a headline or tab would read: Vj cv)u"k# with other parts of the website reading is ok. Especially in the application Vimeo.

I have rebooted computer and confirmed it is something to do with Firefox because when I go and use another platform like chrome it looks fine, no problems.
