I have been using Firefox on my Huawei P29 for several years. I have Google UK set as my search engine and on my home page and this has been fine for years. Two or three days ago when I loaded Firefox Google UK and Google.com wouldn't display. The link flashes in the top bar but the page stays blank. They will load in Chrome and in Firefox if I have desk top mode switched on, but not in android mode. I have uninstalled and reinstalled Firefox, cleared the browser cache but no change. Getting pretty fed up with wasting my time sorting it out. Is it the Huawei phone or Firefox's last update?

I closed all my tabs and reopened the browser bc I was getting lag on sites like X.com when typing my messages. Immediately after opening Firefox again, my homepage, MSN.com was loaded. I tried to click on the arrow to scroll through the different headline stories and nothing happened. I used Chrome & Opera to load the same page and they work fine. This seems like a Firefox thing. I have no extensions or permissions that deny me the right to click on anything. What is the problem?

I am a startup founder. I'm making a webgl rendering engine. I'm doing a stress test with 4 large paragraphs amounting to tens of millions of triangles on a macbook air. Firefox is on the latest version.

When I run the app in chrome/safari/opera, the performance is normal. ~45fps. But in Firefox, it's very slow. My FPS counter (in a requestAnimationFrame loop) says ~45fps on all browsers. But in Firefox, even though the counter says that, the real frame rate is ~3-5fps.

When I try to profile, the problem magically goes away and we're back to ~45fps. I played around with profiler settings, and the key determinant is whether or not I'm taking screenshots. No screenshots = slow. Screenshots = fast.

In the flame graph, in slow mode (no screenshots), it seems like I get stuck in the canvasRenderer and the Renderer mostly waits for it. But in fast mode (with screenshots), the canvasRenderer keeps up and the Renderer spents most it's time in: iokit_user_client_trap

I'm not sure what to do. This is only a problem on Firefox. There's some sort of gpu/threads/something that switches when I profile with screenshots that makes it way faster. This performance hit basically ruins my app for Firefox only. Any idea what I should do?

When I sign in to my bank, placing the cursor in the username box produces a number of username options, including the actual unsername and other mistyped ones from previous login efforts. I don’t want any unsername prompts. I went to Passwords in Firefox and made sure to remove the bank as a site to retain and offer such information when signing into that account. I continue to receive these username prompts. This doesn’t happen with other accounts. I cannot track down where that username information resides, how to remove it, and how to prevent Firefox from retaining this username information for this bank account.

I'm still using windows professional 7, it works for the most part. Unfortunately often the browser won't load or it will load and runs very slowly, then it shows a box saying close previous firefox. When it is running slowly I often have to hit the browser many times until the box shows up saying close previous firefox. Is this something to do with windows 7 or another completely different issue.

How do I add a link to the start page that shows when you open a new tab? I've read support docs and I don't have a "pin icon" on my toolbar... I'm on MacOS (M1) and latest (Feb '24) FireFox...... how can it be so non-intuitive? I can't find an option anywhere...

Hello!

I can't figure out what setting to fix this: every time I click to open a new window, about 35 tabs automatically open up that I have closed several times in the past. I simply want one new window without any previously opened tabs.

I've tried:

• clearing my entire search history several times
• shutting down Firefox and reopening (which opens up all those tabs)
• uninstalling Firefox and reinstalling it
• initiating the latest Firefox updates
• restarting my computer
• turning my computer on and off
• looking through every single preference in my Firefox settings (I've unchecked anywhere it talks about opening tabs)
• reading various articles on Firefox's support page and on other support websites to try to figure this out (there's little info on this problem; the support is mostly about how to save previously opened tabs

Please help! I'm tired of having to close down all these tabs every single time I have to restart my computer or have to shut down Firefox. It slows down everything I'm trying to do.

Thank you!

Hello, sometimes firefox seems like it is working fine, other times certain sites like youtube, duckduckgo and spotify will not load, while others will.

I've gone through and done everything the help articles suggest, nothing happens - then a few days later everything's fine. It's gone on like this for a few months. Any help would be greatly appreciated.

thanks -alex

Hi -- I hope someone can help with this recent problem that has cropped up. Videos that are supposed to be autostart, such as news stories embedded on pages of news sites or video feeding into a side panel on a college sports site I frequent are just continually in buffer mode with the little spin icon in the middle of the screen. This also happens with some, but not all, YouTube videos.

This is a recent development and I didn't do anything to change my setup. I did try updating to make sure I have the most recent version of Firefox, so that's been accounted for. If I close out Firefox and come back to it after a couple of minutes, the problem is cleared, but it only lasts a little while before it begins once again.

Any suggestions? Thanks!

YouTube keeps blanking out at regular intervals. I can watch videos and try returning to the main page, only to load as blank, with only the menu icon in the upper left corner showing. This keeps happening, and the only solution is to close the browser and use Wise Disk Cleaner (or similar software) to clean the cache before restarting the browser. I have to do this several times pr. Day.

I have tried the most normal solutions I have found, already posted, like:

- Disabling Hardware acceleration - Uninstalling Ad-blockers

I have the following add-ons installed:

- Dashlane - Adblocker Plus - Honey - Return YouTube Dislike - Zotero - Express VPN - LeanLibrary

Are there any other options to attempt to correct this extremely annoying problem? I just want to surf YouTube in peace.

Thanks for any replies in advance!

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

I have created a WordPress Website and some of the images are not showing on the FireFox browser. There is no problems on Chrome or Safari browsers. The first image is a screen shot from the Chrome Browser of a section on my website, the second image is a screen shot of the same section but from FireFox Browers. Can you help fix this problem?

The Amazon.co.uk search plugin was working but now its not and when i try to click "add search engine" a box pops up with

Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

another post suggested checking the about:config browser.search.region mine says "GB" which would be correct for .co.uk

All other search plugins work fine. Any suggestions?

Dear Team, I am always facing problems when opening driverpracticaltest.dvsa.gov.uk link. the problem is with both windows and android. whenever I try to open the link it always shows error from website that they have blocked the website for security reasons.

Sometime if i do not get error it redirect me to the CAPTCHA verification but CAPTCHA never loads. no matter how many times we reload the website. I have to switch Edge just to open this website. please do something about it. Thank you

This URL below will return a XML file in Edge/chrome but not in Firefox. I use Joomla as a CMS and it's extensions to display a RSS feed worked fine in both browsers until a couple of months ago. I've tried with a vanilla Mozilla/FF with all extensions disabled but still will not return the XML file
