Firefox Community Forum

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.

I find the 4 boxes on the Contrast Control/Manage Colors settings confusing. I've tried just about everything for an issue I've had for months. When I use the automatic settings there is a dark background. Visited links pops up white (readable) and immediately changes to purple so that I can barely see it. This happens on multiple web sites. Amazon and Ebay are examples.

regardless of changing the search to google- Yahoo keeps coming up as a default. it doesn't even show as an option for search. The article u send doesn't help. I keep changing the setting and chose google - it doesn't work - maybe i should just quitting using Firefox.

Hello,

I would like Firefox to offer the same usability as Chrome when it comes to pinned tabs and session restoration.

In Chrome, I keep about five tabs pinned and always open. When I start Chrome, all my tabs are there, and it shows the last tab I was using. This is smart and logical because it lets me continue exactly where I left off.

Firefox, on the other hand, always jumps to a new tab on startup, even if I was working on a different pinned tab when I closed the browser.

I can’t even begin to explain how frustrating this is. I often work on multiple screens with multiple browser instances, and this behavior constantly interrupts my workflow. It’s so disruptive that I felt compelled to write this complaint.

Please fix this and allow Firefox to behave in a normal, logical way. Stop forcing a new tab to open every single time on startup, or at least give us a proper option to disable this and restore the session exactly as it was.

You’ve made it easy to import everything from Chrome, but without offering this same basic functionality, Firefox feels incomplete.

Thanks

I filled out a registration form to attend an event. At completing the form I clicked on the "submit" button - nothing. Closed the window repeated filling out the form, clicked on "submit" nothing again, no error statement. I could see the "button" react but nothing.

Shifted to another browser, the one having to do with the end of something. Filled out the form, clicked "submit" got an acknowledgement right away.

Any clues?

Why can I not use a shortcut key to slow down or speed up speech. Some things are easy, and I want them to be read fast. Other things require some thought on hearing them, so slow down would be appropriate. And it is inconvenient to have to go inot the options for Read Aloud in order to do this. Besides which, when you go into options, you really don't know whether you have changed the speed the appropriate amount until you go back and listen to the text. As well, I listen to things in English and Spanish and need to switch speeds for these different languages."

Hi folks, I am new here. I wonder if someone could help me solve a new problem which may or may not have anything to do with Firefox itself. Let me explain: a month ago or so, I was running Firefox, and my HP laptop, 64-bit, running Win11, told me I needed to run a new update from Microsoft for my Windows. I forgot that I was running Firefox, and started the update. I live on the West coast of Florida, where there is a lot of lightning... So, right in the middle of the Windows update, lightning took out cable and internet, stopping (interrupting) the update download. The whole neighborhood was affected. Later, when internet service was restored, I re-started the Windows update. Now here's the weird thing: every minute or so, no matter what is or is not running, even before I log into my desktop with my PIN, all of a sudden an old image from a previous Firefox session, complete with tabs, pops up. It then cycles through more images, until I hit the enter button, or tap the pad, or hit escape, exiting the image. It even goes away temporarily if I move the cursor, so trying to X out does not work. A little later, it pops back up. I'm working on a novel, and it is frustrating, because this interruption derails my thought train, complete with caboose. Also, one of the images (static) is my bank page. This spooks me... Please help, someone -- anyone? Ahead of time, thank you!

i was able to download firefox. but now when i click on the icon to load up firefox it says couldn't load xpcom. what does that mean, what do i need to do to fix it?

I'm trying to upgrade from FireFox 128.14.0esr to Firefox 142 on a Mac running Sonoma 14.6.1. Everything seemed to install except for bookmarks and history . When I've done previous upgrades the new FF has automagicaally peeked into the old FF and copied over the bookmarks, including the bookmark toolbar, history and previous autofill info, etc. This time it didn't and I didn't see anything that looked like an option during the install process. It did ask about getting something (I forget what) from chrome or safari; but nothing from the old firefox. The help articles I found didn't seem to tell me what to do. Any suggestions?

Ive been within the past few days getting certain websites randomly popping up first with chrome and now with Firefox ...I've deleted ap0s browsing history to no avail. Even changed my VPN via McAfee please help

Additional information on the problem of not clearing history. It takes from the tool bar at least 5 attempts to clear the Cache, cookies and past pages. The last 15KB of the system cache will not clear. Tried from Setting; Privacy and Security, said there was still 6.9MB, Cleared, check also the past pages box. Came back to the Tool Bar, still has the 15KB in Cache, but settings said there was zero. Not a critical issue at this time. Going forward when you have a response. JJE
