Diễn đàn hỗ trợ Firefox

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?

Hi Everyone,

I’m Harmandeep Singh Kandhari from India, A Health and Wellness Motivator and Now, Recently, my Mozilla Firefox browser has started using much more memory than usual, and multiple tabs cause noticeable slowdowns. I haven’t installed many new extensions. What steps can I take to identify the cause and optimize Firefox performance without resetting my entire browser profile? 🦊💻

Thanks, Harmandeep Singh Kandhari

Hello Community,

I have been experiencing significant issues with Firefox for the past couple of months. The main concern is high CPU and RAM consumption during video playback, especially on YouTube.

This issue started appearing only for the past month or two; it was never present before on the same system, and no significant hardware changes have been made.

Crucially, this problem is exclusive to Firefox. I have tested video playback on other browsers such as Google Chrome, Brave, and Microsoft Edge, and do not face any similar performance issues with them.

Your assistance in resolving this is greatly appreciated.

Thank you.

Unable to run firefox. I get the error message. (see attached screenshot) After terminating firefox processes, I attempted to create a new profile. and see an error message. (see attached screenshot)

The address bar is driving me crazy tbh. I want to search for something from it and it works most of the times but doesn't some other times, and I don't know why. I did try to refresh firefox after you click the helper software to uninstall it, but it still doesn't work all the times, and I also tried this (https://support.mozilla.org/en-US/questions/1337970), yet it still doesn't. I might try to uninstall and install it again but is there anything else I can do if it still doesn't work?

Lost my session. Not the first time, so I went to retrieve it with sessionstore.jsonlz4 Put it in the directory above the backups as usual. Not working. No matter where I put it, Firefox is not restoring my session. Tried everything I can think of, no joy. Would really like to recover my session. Has the location changed? Different file name? Firefox has done a lot of updates lately. I am on a pc operating WIndows 10.

[Lost my session because I had a private window open when I closed my regular window. FYI]

I went to this site, no worries, nothing there but asks you to click...which you should not do. It says to copy the fix and paste it into the windows shell... sounds obvious, it's a scam. Except, this is a major funding company.

So the question is, is this legit from firefox? Or is that what? Go to myforwardsavings.com and you'll see what i mean. Or, see image i have included.

Hopefully someone up the chain in firefox can let me know. As i intend to report them if this is nefarious. Thank you.

Hi

When I use Firefox to act as a browser to search for topics I get the error message

EC_ERROR_REVOKED_CERTIFICATE

I am now having to use "Bing" to search

This has been going on for a long time

Thanks Gareth

I followed [this moderator's post on Support Mozilla](https://support.mozilla.org/en-US/questions/1254142#answer-1207829).

My hard drive lacks space for System Restore, which I forgot to turn on. After I mistakably clicked 'Delete files' 2 hours ago, Recuva recovered these 53 files, too little for a Firefox User Profile ?

Wise Data Recovery recovered 13 files, 108.37 KB, but again too little for a Firefox User Profile?

Webpages don't open on Firefox and a link is clicked (for example, a link in an email). This problem does not happen when using another browser. I followed the advice given to someone who had the same problem. Switching to "No proxy" as suggested did not correct the problem. The advice was from zeroknight and is pasted below: zeroknight 12/1/23, 1:28 AM more options The browser settings are in the menu that looks like three horizontal bars (≡). From there, go into Connection Settings and change "Use system proxy settings" to "No proxy".

Refreshing Firefox did not correct the problem

Hello,

Firefox will not download files. It fails every time me I try. I refreshed Firefox, but that did not fix the problem. Downloads work every time with MS Edge. Please help. Thank you.
