I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks

Hello, when I am on Firefox I am unable to play audio from websites such as Reddit,Twitter and other sites but I am able to do so in youtube. This does not happen to me in other browsers such as brave/edge. Things I have tried are refreshing firefox, turning off extensions, installing windows media pack, trying a different sound device, adjusting sound mixer, allowing autoplay, update drivers. This started happening after I did a clean install of windows. Any help would be appreciated.

Ok, this is a weird one.

I can't load https://duckduckgo.com. It breaks search in a new tab, but I also can't visit it directly from the url. The tab simply does not load.

I've cleared cache, cookies, and extensions. I've refreshed Firefox more than once.

I can visit https://html.duckduckgo.com. I can visit https://lite.duckduckgo.com.

However! In a private window, I can visit https://duckduckgo.com It still breaks in a secondary normal window.

No other site appears to be broken.

I just noticed this today when my browser updated to 136.0.1 (64-bit).

In the Picture attached you can see the tab width changing when playing any audio that brings up whatever that audio symbol is officially called. This also happens when you mute a tab. When unmuting a tab or stopping audio the tab goes back to the regular size.

Is there any setting in the about:config that could stop the resizing of the tab or any setting at all to not have this happen?

Additional info: I have set browser.tabs.tabMinWidth to 140 in about:config. This setting has been this way for years and those tabs with the audio never resized until today.

ATT.NET is blocking my access to ATT/Yahoo email from my ATT.net account using Firefox ''but not using Chrome?'' I have stopped all tracking and cookie blocking

"Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over."

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Update: Codes working fine now for 133.0

I just installed Firefox. What I noticed right away while using it was that fonts were very blurry/hard to read on all web pages, and even in firefox's menus and URL bar.

I attached two pictures, one is a screenshot in Firefox, and the other is a screenshot in Brave. (All chromium web browsers I have tried don't have firefox's font problem)

With reference to my question just posted, also now when I click on my Firefox browser, the Yahoo search engine seems to take over and it won't let me come out of it. Mark

I currently can't stream anything, and this keep getting this message: Widevine Content Decryption Module provided by Google Inc. will be installed shortly,but it never installs.

I have a macbook air and am currently running macOS Sequoia version 15.0.1.

I tried uninstalling and reinstalling, removing extensions, clearing cache and data, unchecking and then checking back again the reproduce drm protected content but nothing has worked.

Hello! I have used Firefox on and off so I don't have a time frame of when this would have started exactly, but I have had some random completely black screens on both of my monitors dating back to at least 2-3 weeks ago that can only be fixed by powering down the entire PC. I've reinstalled my (NVIDIA) GPU drivers, rearranged display-port cables and just about anything before finally finding a fix, switching to edge. So far I've gone a week without black screening when with Firefox I'd get around 4 give or take a week (some days getting to 3 alone). I don't know what could cause it but I have noticed it only happens when first starting a video. Mostly YouTube but other video sites seem to have also caused it occasionally, I would just like to know what could be causing this, as I do prefer Firefox vastly and would like to switch back as soon as I can.

Will provide anything else as necessary!

Hello everyone,

I've been using Firefox for quite some time and I always keep a bunch of windows open throughout a few workspaces on my laptop. However, this takes up a lot of resources and looks very messy. So, I've been thinking of writing a script/extension to simply store all the open links in a window to a named list that I can, then, come back to when I need and reopen. That way, I could possibly have different lists, separated by topic and stored in a single place.

I'm sorry if there is an obvious solution for this, I saw a couple of similar questions have been asked before, but none that I could use as reference.

Thank you for your time, have a nice week!

Hi. Is there a way to customize the order of Firefox headers and footers on printed pages (including print-to-pdf)?

I prefer the header to be url only, in the center. While the footer has page on left; title in the center, and date on the right.

This used to be easy to accomplish with print options in older versions, then -- as the print dialog changed (and actually improved a lot in most *other* ways) I had to turn to about:config modifications like those described in the 1/27/21 reply here: https://support.mozilla.org/en-US/questions/1323433. But now I can't seem to find any way to have any control over print headers besides "on" and "off."

One problem I find with having both page title and url on top is that these can be long, causing one or both to be truncated.

I'm using Firefox 115.3esr.

This problem exists ONLY on Firefox. I vary search engines, from DuckDuckGo to Presearch and Startpage depending on the search results I get.

For no apparent reason I will get a "suspended connection" message on Startpage while using the Firefox browser. I have included both the link and a screenshot of the problematic page. The page will open perfectly several times, and then suddenly, in the same session, if I open a new Startpage tab, this message will appear. While the suspended connection message is visible in Firefox / Startpage, I will try Startpage in Edge, Opera, Chrome and Midori, and they all open to the Starpage beautifully.

I am using the Firefox 125.0.3 browser, I have cleared caches and cookies, and run full malware scans, with zero negative results, and yet this problem persists. It is sporadic, and does not occur on a predictable basis. It occurs whether the Mozilla VPN is on or not, and switching from on to off or off to on changes nothing, even after refreshing the page.

I am assuming that this is a Firefox issue, as the problem does not occur on other browsers

I can easily switch browsers and / or search engines, but Firefox in conjuction with Startpage is my preferred combo. I just find it frustrating in that I cannot fix it myself.

So....Ehhhh...what's up doc?

Hi,

There are two suggestions (or questions if I simply cannot find these): - as the default behaviour of the browser, I want to be able to only see websites from Europe. Somewhere on the net I found that the following address does it: https://www.google.com/webhp?cr=countryAT|countryBE|countryBG|countryHR|countryCY|countryCZ|countryDK|countryEE|countryFI|countryFR|countryDE|countryGR|countryHU|countryIE|countryIT|countryLV|countryLT|countryLU|countryMT|countryNL|countryPL|countryPT|countryRO|countrySK|countrySI|countryES|countrySE

However, when I am trying to use it in firefox as my Start Page, it opens all of these in separate tabs and it does not work. Also as far as I understand using the link is not possible for new tabs.

The reason is simple. For example, when looking for cooking recipes, pages from the USA use strange units that cannot be understood and there is no point in translating each of these manually as all recipes are available in million of versions - it is just a matter of clicks. But I don't want to waste time each time on checking the websites one by one; if the cooking website is from Europe, the units will be of a standard and I don't have to worry. It is the same in relation to many products of any kind. European and American markets are completely different and reading description of something only to find out at the end that it is only available in the USA is waste of time.

- it should be possible in firefox to block some websites or portals by some button. I know that there is an add-on for this but it is only for 10 pages or so, so in reality it is not very useful. It also only works in the way that the page won't open when clicked on. However, it would be much better if unwanted portals or websites were simply removed from search results.

There are too many fake websites nowadays providing incorrect or misleading information. If it happens that I come across one of these, I want to be doing that only once - and block them forever.

I just setup this firefox extension to help me manage my 800+ tabs - https://addons.mozilla.org/en-US/firefox/addon/simple-tab-groups/ . This might have even been causing Firefox to crash and my computer to restart, but I'll save that for a separate issue. The extension has some suggested shortcut keys, particularly Ctrl + Backtick and Ctrl + Shift + Backtick to switch between next and previous Tab groups. I tried to go to Manage Extension Shortcuts in settings, and tried to specify the keys Ctr + Backtick, but the input box would not accept the key. In fact it only seems to accept Ctrl + <alpha-numeric> key. or Ctrl + Alt + <alphanum>

Is there anyway to enable this? Most keys like Ctrl + alphabets appears to be already mapped by firefox's default mappings. my Ctrl + numbers are also similarly mapped by another tab extension to switch tabs.

Thanks, arun

WSJ did some sort of update and now things are broken in the regula browser. I've tried disabling all my extensions, putting multiple sites on the cookies exceptions list and turning off protection in regular mode and it does not work. Private Browsing works out of the box no issues.

The main way to know if you have issues is do you see the stock ticker near the top of the webpage, your name with account info, and some drop down windows. The Live Update sub-websites are broken. I think WSJ on some sites like those thinks I'm not logged in or can't verify I'm logged in.

Its weird. I've had similar things on FireFox before, what is regular mode doing? Why does Private browsing work? Can I somehow "force" the same settings in a regular windows on a per Website basis? This doesn't seem possible at this point.

Two issues:

1. History is truncated, does not show all history even though Custom Settings set to remember. One google post said to 'delete all history upon closure' ... There are many, many posts from users having same issue.

2. Whatever history is being recorded is no longer simply a list (Ctrl-H) but is sorted into Today, Last Week etc. which is both annoying and makes searching for previously located site impossible unless you know WHEN you visited (unlikely).

Why was the changed? And why don't you change it back so when I select History, Show All History from task bar, Firefox would do just that?

I have always set my option for all download file types to "Always Ask" and now Firefox not only asks me where I want to save the downloaded file, but also downloads a copy to the Windows Download folder. Why am I getting double downloads? I only want one copy of a downloaded file, not two copies. Now I have to go to my Windows Download folder and delete the duplicate downloaded files. My question is, if my Firefox download option is set for all file types to "Always Ask", then why are you downloading the file twice??? I have specific folders where I want files to reside. I don't want to have to remember to go to my Windows Download folder and delete the duplicate files. How can this duplicate file download problem be fixed?

Long time user, Leo
