Firefox Community Forum

I have a question (speculation) about having several Firefox based browsers installed on my Windows 64 PC.

I have a Windows 10, 64 Bit PC with 64 Gigs of RAM. I've always had a habit of installing several versions of Firefox based browsers - all to no avail. However, as of recent, I'm finding that my browsers begin to slow down substantially after 15 minutes or so of browsing - please read on.

Right now, I have the following 64 Bit Firefox based browsers installed on my PC - they are:

Firefox Waterfox Floorp Librewolf

I have quite a large amount of bookmarks saved, and I make sure all browsers have the same bookmarks.

I have a half dozen or so of add-ons, and have tried - from time to time - to uninstall various add-ons to see if they were the cause of the slow downs, but none of that made a difference.

For example, let's say I'm browsing for 15-30 minutes or so, and have a half dozen different tabs brought up. After awhile, things begin to slow down substantially such as delays in clicking on links and having it respond, or right clicking, etc. Browsing speeds slow down substantially also.

Here is what I then usually do:

1. Create a new tab and type in "about:memory" and click on the save memory command.

2. Go into settings and delete cache.

This normally does nothing to speed up things, and I find I have to just close out the browser, wait a few seconds, and bring it back up to things to get back to normal.

This has me speculating - "Could" it be that having a variety of Firefox based browsers with similar data conflict with each other in some strange sort of way" Or is it something else? I know that having a bunch of tabs up can deplete memory usage, but as I mentioned above, I have 64 Gigs of RAM and never had this issue before.

My SSD drive has 500 Gigs of storage, and only half is being used.

Any suggestions or recommendations would be truly appreciated.

For about a year I have, several times, tried to use a link or a pop up that doesn't work in Firefox but can be accomplished in Safari. Today, I used a credit card to pay for something on the UFT.org website. It worked. I needed to make another purchase on the same website and page but I got a message that there was an error with my credit card info. I tried again. I tried another credit card. I signed out and back in and repeated everything and still got the same message. I copied the url, went to Safari, pasted the url, entered my info and was successful in making the payment. I am using Firefox 133.0.3. What might be happening to cause these problems?

I have checked that DRM is allowed - it is

I have rebooted my system and cleared my cache multiple times.

I just installed Firefox today.

No streaming service works. Not Prime, not Netflix, none of it. Only YouTube or other free sites. I'll hear audio only, but get stills or black screen for video. I've logged out of those sites, cleared those sites individual cache and cookies. I have disabled all add-ons for the streaming sites. I have ensured that autoplay is enabled for Firefox.

I don't know what else to do and I am in some distress over it. Any suggestions would be appreciated.

Hi, I'm using FF for year for development and had several problems with cached data in this time. Now, since the last update (automatic update yesterday), Firefox is caching my js for localhost and ignores nearly everything to stop it.

F5 and Ctrl+F5: no effect Enabling "Disable cache" in devtools: no effect changed about:config (no effect): browser.cache.disk.capacity 0 browser.cache.disk.enable false browser.cache.memory.enable false devtools.cache.disabled true

Only going to settings > privacy + security > Clear Data helps. But as you can imagine, that's really bad DX

I tried a FF-addon for clearing css cache, but it's outdated and doesn't work.

Is there anything I can do, to disable cache for localhost?

I don't understand why this aggressive caching problem is ignored for years and gets worse every year! Why are settings like "Disable cache" in devtools so broken? I tested other browsers and have not found the same issues. I don't want to switch browsers! I just want a cache free localhost! FF can cache the sh*t out of every webpage. But please leave localhost out of it!

I want to be able to see the full text of my specific bookmark. My bookmark says "First National Bank of Huntsville". At present, it shows "First National Bank of..." Is there a way to do this?

I am receiving the words403 Forbidden when I try to connect a website that I use regularly and do not understand why this is so. Please help me to be re-connected.

All of a sudden, I get a "Not enough room to save" error message when I try to download a fill. There is plenty of room on my disk.

Also, it's not giving me the option of just opening the file.

I've been needing to use Edge to download files.

outrageous, i moved from windows to debian for the purpose of exceling my ram capacity on this low spec netbook with 4GB 3.7GB usable with emmc chip and a celeron n4000 cpu turns out ff eats just like in windows.

I am not an expert just savy, remember the time when upgrading from 32MB to 64MB was a big leap? well where the hell did 4GB of ram became obsolete? so there's no windows conspiracy just exponential ram usage?

Is there a different version of FF i could use for this 4GB machine? non-upgradable I could always try vivaldi or look else where but i trust FF for base security. I am using ublock origin on the machine too and 1 custom theme but i doubt that fixes the root cause. Is all the internet in the 2020s this ram voracious beast?

upon loading a empty tab FF uses 500MB for itself forget about the 64MB system ram from the 90s is FF 2025 really so complex or is this a conspiracy? then i load startpage.com and it uses 200MB!! of ram just on that search form man.

The UI font on Firefox UI appears to be corrupted. See screenshots attached.

The app was installed recently and not used much. When I launched it today the font appears like this. No other apps are affected.

I only have a handful of custom fonts and none overwrite any system fonts.

Hi, I have 32 gb of memory in my system and I'm having an issue where firefox is taking up most of it but only reporting 1 or 2 gb in task manager. Im using the windows powershell command Get-Process | Sort-Object -Descending WS | select -first 1 | select -ExpandProperty ProcessName to find whats using the most memory and its listing firefox, heres a screenshot showing the issue.

Hi My normally excellent Firefox on Windows 10 has suddenly become unworkable,with the "Gah Tab Crash" message now coming up almost constantly. I have tried opening the browser in safe mode but to no avail. Any suggestions to travellinbilly@gmail.com. Fingers crossed.

There is a similar (but not identical) topic on Mozilla Connect , and I posted there. But I did not get a response. So I am re-posting on this new topic on Mozilla Support. I have a similar problem to what was discussed on Connect. I am using Firefox 133.0.3 on Windows 10 Professional. After Firefox has been running for a while, I get a message from Windows 10 that the free space on my C:drive is low. I did a directory listing on my C-drive before and after Exiting Firefox; I saw no large files disappearing. Then I decided to do "dir c:\ /ah" to see hidden files. What I saw was that pagefile.sys decreased in size from 29,925,748,736 to 16,270,770,176. This was a decrease of 13.7 Gb. Is this normal? I have lots of windows and tabs open in Firefox. Thanks.

I recently (A few hours or so ago at the time of posting this) realized that whenever I right clicked on anything, no matter if it was a link, text, image, or nothing at all, the menu that popped up showed basically every single possible option.

I do not know if anything would actually happen if i tried some of the options on the wrong file types and such, but I have noticed that trying to use some of the options that would appear and work normally before (like copying a link from a redirecting image), no longer do anything. Copying images seems to work, as well as cutting, selecting, searching terms on google, etc.

I do not think I did anything to cause it. I was using my computer normally for a bit before noticing and I think I would've noticed sooner if it was messed up from the start. I also don't remember if my firefox was updated recently, but there were no updates queued when I checked (Currently at Version 134.0).

The image attached is what shows up when I do nothing but click on the background image of the default home page.
