Firefox Support Forum

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?

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.

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

In the recent update to Mozilla, all of my shortcuts disappeared. I had many, and can`t remember them all. Is there any way to restore my shortcuts from what they were a month ago? If not, I will switch to Edge.

Am getting the 403 error message when trying to log on to a news site which was previously accessible. I can access the site from another browser but not via Firefox. What could be the problem and how do I fix it? Thanks

Okay, I am unable to get into my bank online even after doing steps to fix Error code: PR_CONNECT_RESET_ERROR checking the site, it says this is at firefoxes end

I'm not sure where the issue is exactly, but I suspect its something to do with different standards of storing images in clipboards.

If you see the images, this is a screenshot of an Excel grid, taken using win 11 snap tool (shift+win+s). I paste this into paint.net (5.0.12) Then select all and copy/paste into Confluence using Firefox. The edges of the images are either shifted, or a line is added.

If I use paint instead of paint.net, it is ok. If i use edge instead of Firefox, it is ok. Saving the file as png and importing it and its ok. Pasting from paint.net into powerpoint and its ok.

Any ideas what is causing this or how to fix it? I'm going to ask atlassin (confluence) and paint.net help as well.

How do I disable the mozilla.com news popups? I keep getting annoying news popups with Mozilla.com written at the top of the popup. Todays was USAToday. I did not request this and I want it gone.

I loaded the postcode lottery website but it's completely blurred. I last checked the same website last month, and it worked fine. I have cleared the cookies from Firefox, but the result is the same. It appears clear for a moment, then blurs. No pop-ups asking to accept cookies. It works fine using Chrome. Any idea why Firefox won't display it properly? It loads the National Lottery website, so it's not about gambling sites I guess.

basically just the title. In the last couple days youtube.com specifically has been borderline unusable for me on firefox. All other websites work fine for me on firesfox and youtube has no issues on other browsers.

I frequently open new tabs by right-clicking the current tab and choosing "New Tab" from the context menu. Naturally, I want to start typing a URL or search term.

But the focus/cursor/caret is nowhere and typing does nothing. I have to click on the address bar, and then I can type.

I'm not using New Tab Override and I have Firefox's new tab set to a blank page.

I tried disabling all my add-ons, but I still had the problem.

I tried setting new tab to the Firefox home page and for a short while I got a cursor in the address bar. But the problem returned after a few hours

Any clues on what might be wrong? Firefox version 120.0.1 (64-bit) on MacOS Ventura 13.5.1. Thanks!

(A similar problem is described here: https://support.mozilla.org/en-US/questions/1420220 -- but in my case this is not a container tab.)

I had ~500 saved logins on Firefox prior to it updating to version 121.0 - now I have 15.

Firefox Lockwise app on iPhone still shows all my saved passwords.

How do I get these back and why have you deleted them?

Can not login to my PNC Bank after Firefox update 121, another computer could ling in until it to was updated by 121. I can login with Edge. Windows 10 (up to date), 64bit, Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz 3.50. I get, see attached screen shot, only when using Firefox 121.

When selecting "Open in Firefox" in the "What do you want to do with this file?" box or on about:preferences and then opening a PDF file on the web, instead of downloading the file to RAM and opening it with its online address, Firefox downloads the PDF to /tmp/mozilla_${USER}0 and opens it from there. This also adds it to the download history. I have set the about:config flag browser.download.start_downloads_in_tmp_dir to true so the files I just open and don't want to permanently download don't clutter my $HOME/Hämtningar (downloads) folder. I tried to first prevent that by selecting the default action to do when tasked to open a PDF, but that didn't fix it, so I set the about:config flag. Unfortunately, setting the default action stopped Firefox from opening a PDF inline without downloading it and I cannot find any option along the lines of "Preview in Firefox" (as described in this support article ).

With 'Back up your Firefox data' it says it saves all open tabs.

What is meant by 'open' tabs? Is it tabs that I have clicked on during my session?

I have just over 300 tabs, will Firefox save all of those tabs in the cloud or only the tabs I clicked on during a session?

I am trying to migrate from a very old version of Firefox (v. 55) to the current one, but there is an app that is more helpful to me that all the other features combined. That is the "Tab Grouping" app that will not run in any version of FF higher than v. 55.

In my work, which often includes a tremendous amount of research, I need to be able to quickly go from one group of tabs to another. If I had to open all these sites manually, that would take the better part of the day and frankly I don't have near the mental capacity to remember the tremendous number of tabs. I have had a couple replies (Thanks!) to this question sometime back, but unfortunately none were even close in performance.

So, can anyone direct me to an app that will allow very quick movement from different sets of windows/tab groups (please see screen shots below)? Is there anyway that I can get this app to work in Legacy mode? I have several other old apps that work perfectly well in this mode.
