Firefox Support Forum

I started getting this message today - "this page is slowing down firefox. To speed up your browser stop this page" How can I fix it other than to start using Safari.

Your instructions under "help" say to click on "Firefox" and click on "preferences". When I click on Firefox the menu does NOT have "Preferences" in it. What's up with that?? And how do I clear the cache and cookies?

This problem occurs on My wife's and my machines. My wife has a printer. I do not. When we try to print the preview shows only a few lines or at best a half page. Even if we want to print multiple pages that's all that shows up. We have "print all" as the default setting. The problem started about a month ago. I think it has something to do with the newer versions of Firefox.

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

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 is the message I get. "Please unblock challenges.cloudflare.com to proceed." I can do nothing.

Things I've tried. Adding exceptions in the privacy settings in 2 seperate areas. Resetting Browser deafults. Turning off all vpn's and addons.

Nothing works.

I have been using FF for many years but recently have started having issues on eBay.co.uk

At the moment it specifically relates to leaving feedback on my sold items.

I'm currently logging in on MS Edge or Chrome to leave feedback as FF just will not work.

I've tried FF on a clean install on a 2nd PC (no add-ons) and still get the issue.

Please help as I am now having to use Edge & Chrome so much I may as well move over to them which I would rather not do.

If I go to Safelite and start scheduling an appointment, navigating through that set of webpages will cause my computer to green screen/crash. The landing page at https://safelite.com asks for a zip code, and submitting that form puts you into the scheduling flow; after entering some details about a vehicle, I can click back and continue a few times (less than ten) to make my computer crash. I was able to reproduce the issue in troubleshooting mode. I also tried the same steps in Chrome, but it did not produce a crash.

This computer has had an issue with crashing in this manner for a while now, but this is the first thing I've noticed consistently causes a crash. I'm not expecting a solution, but I am hoping to close in on the issue; whether or not Firefox is the source here is questionable, but it does seem highly entangled.

After after update to 121.0.1 on Ubuntu, I'm not asked anymore for Primary Password at startup, hence I cannot use my saved logins and certificates. If I restart in Troubleshooting mode, I have the pop up for Primary Password back, which is working as expected. Restarting normally after disabled all Add-Ons does not solve the problem.

Been using Firefox for years. Also reading Foxnews. Starting yesterday I cannot post any comments at the site. I can go to Edge and all works fine, so there is something with Firefox that is conflicting with Foxnews. At first I was not able to even read articles but removed all Addon's and that has been fixed--even after reinstalling all Addon's I can still read articles. I log into my Fox account and the webpage reflects that but when I try to post a comment it says I must sign in to post, yet I am signed in! However, I go ahead and follow the links to sign in (check e-mail/click sign in to Fox etc.), ultimately it tells me I'm now signed in. But when I go back to the comment section it still says I must sign in to post but I am signed in. Besides removing Addon's I also tried removing the FF browser (Win 10 recommended a refresh instead of uninstall so I did that). No help, I'm thinking whatever is causing the conflict when refreshing FF the sync simply puts the conflict back! I'm still requested to sign in when I am signed in! As stated earlier my Fox account in MS Edge works fine.

Is it possible to customize the URL pulldown? When I click in the URL window - I am presented with 6 website options along with various web search options. It would be helpful to modify the options since none of them apply to me. I tried deleting history, playing with the settings/search suggestions/change settings. I want to specify certain websites - and leave it that way. I've tried right clicking the site, shift deleting, contrl deleting. Nothing works. If it is possible - it is not intuitive. I notice that the list does slowly seem to update and evolve depending on where I have been. But I don't want that either. Thx IW

In the last few days whenever I download a PDF file instead of it being displayed in my default PDF read Firefox (version 121.0.1) takes over and displays the contents of the file. I do not want this, I prefer my PDF reader! How do I stop Firefox trying to take over this function? (other than converting to Chrome)

We can access the website www.focusadhdindy.com using Chrome, but when using Firefox, we notice that it requires an additional '/' (www.focusadhdindy.com/) to open. Please resolve this issue so that the website can be accessed from Firefox using the link www.focusadhdindy.com without the need for an additional trailing slash.

I just upgrade my firefox, but it did not import my history, cookies, bookmarks or passwords. I found a backup of the bookmarks (in a bookmarkbackups folder) but how do I restore the everything else?

Whenever I go to a Google page (tested on Google.com Docs, Sheets, Forms) the page crashes. The issue started sometime around this afternoon.
