Firefox Community Forum

I am running the latest update for Firefox (143.0 (64 BIT) on a Windows 10 Dell laptop. Since the update on August 28th (prior update), my browser has been extremely slow, even with only one tab open. Task manager shows 95% memory usage after 15 minutes of browsing, and I have to end task on Firefox, then reopen the browser. I have run my Webroot antivirus and Malware Bytes, and my laptop is coming up clean.

I am not fond of Microsoft Edge, but I wanted to see how it performed. I have no issues with speed, so I can only guess that this is a Firefox issue.

Are there any known issues with the August 28th update?

the last 2 times I have allowed firefox to update my computer, it moves my icloud file to trash, the last time this happened to get my icloud to work I had to reinstall the Icloud on both of my computers and then replace the files. Why does this system always want to update?

"If there is a problem with how this image is displayed, view it in a browser" Always goes to Microsoft edge by default. How can I make Firefox the default for viewing email messages in my browser?

Hello, the zoom returns for each tab at 120%. Does not take into account 80% changes. Parameter 80% by default for ZOOM. I reinstalled firefox completely without success. With each new Tab goes back to 120%. I have a 65-inch screen. IT'S HUGE.

THANKS

Since the newest wave of firefox updates my icons on startup are gone. When i click new tab they show up again or when restarting the page. I tried reinstalling firefox & changing icons with no help. The previous update before 141.0 had no issues. I tried searching around and didn't find anything helpful. Anyone else have this issue or know of a fix?

As in if not minimized just the once, the taskbar doesn't unhide when I move the cursor all the way to the bottom.

It happened earlier this year, an update fixed it, and it came back some updates ago.

Is there anything to configure in the about:config to alleviate this issue?

Many thanks!!

I don't think any of the above topics relate to my question.

When I am typing an email (AOL), I type for awhile and then all of a sudden, the cursor just disappears. I have to point my mouse again and click to get it back. Then I type again, and all of a sudden it again disappears. I have read articles, etc. but nothing seems to help it. What is the problem and how do I fix it? If I switch to a different browser there is no problem; only in Firefox.

Thanks, Kathy

I'm using the AI chatbot in Firefox Developer Edition's sidebar and I was wondering if it's possible to set the web page from the active tab as the context by default for all future chats.

Is there a setting (checkbox) for this somewhere?

The scrollbar slider isn't displaying correctly. If I grab the screen, zoom in, and look very carefully, it is possible to see that the slider is a very slightly different darker shade of grey to the rest of the scrollbar, but it's almost impossible to see, so something is clearly not working properly here. The scrollbar should be highly visible as it's the most often-clicked control of the entire browser.

Hi, I set up the vertical tabs and I like them. However they're very unstable and so is the tab sidebar. The expand on hover feature only works for a short time. Then the x to close a tab disappears and the sidebar gets stuck open or closed. If it gets stuck open, it covers the settings and AI and history sidebars so I need to close it manually to use them. Yesterday I lost 3 of my 6 pinned tabs. After closing and opening FF, they were just gone.

Also my tab groups will suddenly disappear. This started in the previous version and still happens, and I lose the sites I had collected. Plus FF has been very slow to load.

So yesterday I gave up and reverted to horizontal tabs. Like magic FF suddenly worked perfectly and very fast. I'm not enough of a techie to have any idea of what is causing what and would really appreciate any advice.

I really like the possibility of unloading tabs but still have them visible as I need to be able to backtrack some searches which are many levels deep. One thing I have discovered however, is if the tabs are grouped, you cannot unload them and that poses a problem for me as I have many many tabs that live in various groups across my tab bar. Is there any way of unloading these tabs while they reside in a group or is there a workaround I have not thought of yet?

Cheers and thanks everyone for your support and suggestions ....

bold text I thought I had messed up my Firefox home screen somehow, when I deleted cookies and data (I am 84 and not techy, and not keen on changes!), but now I see that an update has done it. I want my old home screen back, with the 'previous tabs' feature restored instead of the 8 bookmarks that now occupy that space, most of which I rarely use. How can this be done, please?

 I'm using Windows 11

Hi! Firefox now has two profile managers. The old one can be used so that I can open two Firefox instances with different desktop files on Linux with the "-P and --no-remote" command line flags. Is this also possible with the new profile manager in Firefox that came with version 138, which is similar to Chrome's? With Chrome this can be done with the "--profile-directory" command line flag. Can't find information about this. /Regards

Hi, I wanted to reduce height of tabs and remove borders in file userChrome.css.

So far this works for height, but was wanting to know if a negative value can be used to reduce further, Also tried some code to remove radius but it didn't work. Remove radius for selected tab and also hover on tab.

/* REDUCE HEIGHT OF TABS (VERTICAL TABS) */ .tabbrowser-tab { min-height: var(--tab-min-height) !important; max-height: var(--tab-min-height) !important; }

Why in many articles the Reader View access button in not enabled in URL right hand side. For example

iOS 26.1 on an iPhone SE; Google Maps 25.47.0. Links to apps don't open in-app. If I click a Google Maps link, it sends me to the App Store. If I click a link to Instagram, it sends me to the App Store. But I already have those apps! How do I make it work like it used to?
