Firefox Community Forum

Just recently when logged onto Hotcopper.com.au have been getting a message that reads "This page is slowing Firefox down. To speed up this browser, stop this page." There is a STOP button, that helps for a moment or two only. When I open the program with MS Edge, the problem does nor occur. I was going to remove the Firefox App but saw the repair option. Repairing did not stop the problem. Any suggestions? John I have a near new Acer laptop running Win 11.

To preface this, I am not sure if this is caused by my OS (Ubuntu 24.04) or by the way Firefox tends to work on Linux as other issues have been (and therefore, might be resolved with a change in about:config).

Problem: When I download a file and download another one right after that one, the window showing the folder I am choosing to download to won't show the file/image preview of the file I just downloaded before; it only shows the correct preview once I have opened the file manager on my OS; after doing that the file preview is up to date again. (basically, it only shows the correct file preview when I viewed the files on my desktop before opening the download window and will not keep up to date with the most recent changes on its own like it does on Windows for example)

Most of the keyboard shortcuts are not working. Copy-paste works, but others for example, Ctrl + F doesn't work. Very confusing and frustrating. Attached is the screenshot of Browser Console and it does show missing attributes. Not sure if this is a browser issue (currently using 147.0.3 (64-bit)) or I need to make certain change settings. I would appreciate any suggestions to resolve this issue.

Kind of a combination 'Browse/Download problem. This morning on rising, 07/11/25, Claude.ai's html artifacts quit loading on Firefox. Doesn't matter whether I'm on laptop Macbook Pro or iMac...or iPhone...but it loads in Safari and Google Chrome? Site is fine...document artifacts are fine...but html sits with spinning wheel?

This is a bit of an odd question, but I'm gutted. I have pretty severe OCD and AI tools have become very problematic for my reassurance seeking behaviors. I just got all of them blocked using tools like coldturkey and screen time. Now as of this update they're all in my firefox sidebar, and so far I see no way to block, only hide them (the trouble here is I know it's there, if I'm feeling a compulsion it's incredibly difficult not to follow through). Is there any iron clad way to block this? I hate how hard these things are being pushed!

After the latest Firefox update I've been unable to bring up all the bookmarks I had. I also lost bookmarks on Toolbar. I've followed posted recovery suggestions but haven't had any success retrieving bookmarks. Has this happened to anyone else? What do I do?

Hi there my default browser is Firefox Mozilla but certain sites open very slowly or not open at all. All things I did were clean the cache, reinstalling Mozilla software but nothing works and its a bit frustrating. Also Adblock Plus wont work on you tube. Thank you in advance Kuba

I’m currently experiencing an issue when trying to use Membership Anywhere through the Firefox browser. Membership Anywhere is a digital membership management platform that many organizations use to manage memberships, events, and member interactions efficiently. While the site works fine on other browsers, certain features, like logging in, accessing the member dashboard, or completing payments, do not function correctly in Firefox.

Specifically, I notice that some pages fail to load completely, and certain interactive elements, such as buttons or form submissions, don’t respond. I have tried clearing the cache, disabling extensions, and updating Firefox to the latest version, but the issue persists. This problem is affecting not just my access but could impact other users of Firefox who rely on Membership Anywhere for managing their memberships digitally.

I wanted to check if there is any known compatibility issue between Firefox and Membership Anywhere, or if there are specific settings or security features in Firefox that could interfere with this platform. I would greatly appreciate guidance on how to resolve this issue so that I can continue using Membership Anywhere smoothly without switching to another browser.

I use the est edition of firefox 115.15.0 64bit and after the last update i can't change resolution to any youtube video. Why is that happening and how i can fix it?
