Diễn đàn hỗ trợ Firefox

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.

hi, I recently purchased a new wireless mouse and keyboard... and my only problem is that there are a couple extra buttons on my new mouse... roughly thumb position... and are by default set to navigate backward and forward.... I'm running ubuntu linux... which results in accidentally clicking back midway through a video or podcast and losing my position more often than you'd expect... any idea how I might either reassign or disable them entirely on the software side of things? thanks. -dan

Hi,

I started to notice recently that calendars in some websites I browse with Mozilla are inaccurate. The dates like months, days,... are in a mess. Then I used Google Chrome instead of Mozilla and it went right. It was accurate with Chrome browsing those sites. Did you hear of the same problems with Mozilla ? What can be wrong ?

Thanks for your insights,

All the best,

Denis

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

Windows 11. I have my taskbar behaviour set to ‘Automatically hide the Taskbar’ So usually the Taskbar is not displayed, but when I move my cursor to the bottom of the screen it reappears. With Firefox I cannot make the Taskbar reappear.

I was excited to receive the new Tab Groups feature and am now disappointed that it's not working and I've 'lost' dozens of tabs.

Here's what I did: I created several groups by right-clicking and added tabs to each of the groups. Since it appears that only way to collapse a group is to "save and close group," I closed each group. Now they are all gone. When I right-click to create a new group or "add tab to group," the closed groups are nowhere to be found. Plus, I do not see a "list all tabs icon" on my toolbar to reopen the grouped tabs, which is what [article] says should happen.

Suggestions for making this work?

After the most recent update on the 17/09 my search bar is permanently stuck blue (screenshot attached). Any idea how to revert this back to the grey it was before.

Dear Helper,

since the newest Firefox update, i got today (16.09.25), the audible cloudplayer doesnt work anymore, meaning it wont load the audiobook! I emptied the cache, but nothing changed. I tried the audible cloudplayer with Windows Edge and it works fine, so it is a Firefox specific problem. I granted all websides access to audio and media automatic replay, nothing changed. The cloudplayer doesnt work! So my question is: What else is interfering in Firefox with the loading of the player? Thank you so much in advance for your help :) Yours sincerely David

Suddenly today I can not open "You Tube" and I have no Idea why. I have not changed any settings since last evening when it worked fine and have tried to access it, unsuccessfully, in several different ways..

Hello,

I can no longer log in to iCloud applications on Firefox . On my iPhone 11, I receive the request to log in to my Apple account. I followed the same steps and was able to do so on Google Chrome. Attached is the error message.

Thank you in advance for your feedback.

I am unable to sign into the iCloud web page on Firefox. I can sign in on Microsoft Edge, or on the Safari browser on my phone, so this is clearly a Firefox specific problem. When I try to sign in, the page skips the option that verifies my identity and goes straight to a message saying "Failed to verify your identity, Try again" without allowing the verification to occur. The verification would occur if the page would allow it to, as it does in the other browsers I mentioned. This was working fine last time I logged in a few days ago, so this is a new problem. I could switch over to Edge, but would prefer to use Firefox, if I can. Please help me. Thank you.

Suddenly, I can no longer log in to iCloud on my MacBook Air from Firefox: I get the login alert and the code to validate the connection, but the window to enter the verification code doesn't appear. It says "enter" the code, but I don't get the window to do so!

I'm on Big Sur 11.7.10, it worked without a hitch for years. This laptop is one of my trusted devices. Is a recent update preventing the connection?

I looked at similar questions, and answers from 2020 said to add the 6-digit code after my password, but that solution doesn't work.

It seems the problem is with Firefox; it works on Safari. Any solution for Firefox?

Thanks
