Firefox Community Forum

I only opened 5 pages (fixed tabs), and only enabled two plug-ins, Proxy SwitchyOmega and AdGuard AdBlocker. The browser was always open, and the pages were static, and nothing was playing. The strange thing is that it didn't take up much memory at the beginning, but it took up more and more memory over time. Today the system got stuck and couldn't respond (it might be that the system used virtual memory).

I used the browser's task manager, which showed that the Shared Web Process memory of several pages was very high, some as high as 4G, and the GPU memory was also higher than before.

I think this is very strange. Why does the memory usage increase exponentially after the webpage has been there for a while?

My settings and usage habits have basically not changed. I didn't have this problem before, but it has appeared in the past six months. I have updated many versions, but the problem still exists. I have always used Firefox. If it continues like this, I will be very disappointed and have to make changes.

When I startup FireFox, it takes ~15 seconds to show me an page. After loading, it works normal and loads pages within a second, until I completely close the browser, and then the first page again takes ~15 seconds. I've been having this issue for the past few months.

- I tried disabling all my addons - Launched FireFox in troubleshoot mode - Deleted everything in DataReporting\Archived folder - Cleaned out History/Cookies and site data/Temporary cached files and pages - Tried both Default and Max protection for DNS over HTTPS - FireFox is allowed in Windows Defender firewall - Tried setting 'browser.cache.disk.enable' to FALSE - Tried changing 'Enable HTTPS-Only Mode in all windows' to 'Don’t enable HTTPS-Only Mode' - Windows and FireFox are up-to-date

None of the above saw any improvement in loading time.

There is a website https //secure.exeloncorp.com/login that will not load using FireFox. It will load using Google Chrome. Is this a function of the Website or FireFox? Is there a setting in FireFox that will fix it?

Hi, It is not a question but a bug report. From the version 131 up today the Nightly stopped to initialize quickly as before. Certainly, it is not the windows 10 21H2, the antivirus, the firewall or anything other similar internal problem, just because the Edge and the Opera are working fine and they are four times more rapid than the Nightly. It is just to say, that your procedures to improve the security is transforming the Firefox in a mirror of the usefulness Chrome. I take the time to open the home page of Firefox = 9 seconds, against 0.28 s of the Opera. So, I think you should rethink the security and other hidden setting options of the Nightly, because as is, it is very bad. The big thing that the Geeks from silicon Valley did not have in mind is: There are lot of people that need to find extremely fast a configuration, like to export/import passwords from older browsers, or computers, without need to replace one by one. There are many other things that you decided to hide, but I don't know why. Anyway, I will try to update one more time, then, unfortunately I could not use the Firefox anymore. Further, I want a few add-ons, either if there is any percentage of insecurity. A few times we need afford risks to understand and discovery other problems in the web. We cannot do it anymore with the Nightly.

Unable to use Firefox to access Youtube. Problem started either late last night or early this morning. Whether using a bookmark or entering "Youtube.com" manually, the browser window merely acts as if I'm not even connected to the internet before finally just giving up.

Have tried using both 115.17.0esr (64-bit) and 132.0.2 (aarch64) versions of Firefox (each using a different computer), but YouTube refuses to load.

By contrast, YouTube has absolutely no problem loading using other browsers, the site loads almost instantly.

This happened too much, like 6 times when using firefox in this month. I dont want to shut the program because I got unsaved notes in it. I was listening to music and it just began to play it non stop. and it dont respond.

I try to restart network or suspend the process nothing works. If I could make firefox reopen to it's original state+ cookies; no site reloaded and get back my incogico it would be much appreaciated. ALso everything was saved in firefox since I did not end the task, I dont want to lose those.

Hi,

I cannot seem to close a tab, usually the last one I opened, in my browser window. It remains at the upper left hand corner of the browser. Please note the tab in the attached image.

How do I close this window and prevent this behavior again?

Many thanks,

Lisa D

When I type in the search bar, for example, 3+3 (also tried 3 + 3), when I enter, it will give me this "3 3" and will just show results instead of the calculator.

It, however, still work normally if I were to write "3 plus 3"

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

Hi!

I've noticed dropped frames in videos for a while now, but only recently tested the issue. Using youtubes stats for nerds, I found that when videos have a small viewport resolution, it starts to drop frames. (I would test with other sites but only know of youtubes stats for nerds system to detect issues like this) For example a viewport resolution of 1250x703 does not drop frames, however by unmaximising the screen and the viewport resolution drops to 681x383, it begins dropping frames.

Using my 2nd monitor which has a smaller actual resolution, the video drops frames unless fullscreened, see recordings below. Test A | Firefox Maximised but video not fullscreen Test B | Firefox Maximised and video fullscreen This issue also occurs with picture-in-picture mode.

Disabling hardware acceleration fixes this issue but for some reason only affects firefox, using MS Edge with "graphics acceleration" enabled does not result in this issue. Is this potentially an issue specifically with how firefox handles hardware acceleration? Also since I require hardware acceleration to be enabled for 3D model work in my browser, is there something I'm missing here that would allow me to keep hardware acceleration on but not have this issue?

Any help is much appreciated, thanks!

I use a program called "URL Manager Pro" on the Mac to manage my bookmarks in all my browsers. Double clicking on a bookmark icon in URL Manager can open the URL in a new tab, the same tab, or a new window depending upon how I set the preferences in URL Manager Pro. This works fine in Safari. However, in Firefox, the website opens in a new tab regardless of how I set my preferences in URL Manager.

The author of URL Manager tells me the issue is a problem with how Firefox deals with AppleEvents. It's very annoying to accumulate so many unintended new tabs and then manually close them. Is this fixable in Firefox or is there a work around?

Thanks

Hello,

I created a 1+-minute video on my YouTube channel and then posted it to my GoogleSite. But Firefox will not allow it to play because it is embedded from another site. Can you kindly help me understand how to get around this?

My goal is to create content on YT that only I can embed on my site. Yet it does not seem that there are options allowing for this. My desire is to share some wondrous FREE visual content AND to protect it by funneling it to my site.

Please know that I am not a techie as you most likely are, so your explanation is appreciated. And your assistance! Thank you. MC { yt is @ starbrightone7 } { website is wwwDOTharmoniccoherence.co ... the ABOUT page }

The thumbnails can be momentarily seen but within less than a second they disappear. Not happening in edge so doesn't seem to be a computer setting. Cleared all cookies and cache in firefox. No different. The attached image shows the pictures that are missing in firefox. Image taken from an Edge search.

Thank you in anticipation. Steve Balderson

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)

I run a Synology DSM server on my local network. The website page to load locally inside my LAN is along the lines of 127.0.0.1:1001.

MacOSX 15.0.1 FireFox(FF) 132.0 (aarch64)

Previously accessing the DSM via the local IP address worked fine with no problems. Now, following one of the last couple of FF updates, I get an "unable to connect" message.

I also have a domain that routes to my local server and I can still access the DSM via the internet http address through FF. So I know that DSM is running fine and I have verified the settings within DSM.

I can load the DSM via the local IP in both Safari and Chrome. Only FF says it's unable to connect. So that shows that my DSM settings are fine and the page is available and loads in Safari and Chrome via the local IP.

I searched the forum and found similar postings, but not quite the same issue as mine. I deleted the cache & cookies/site data. I ensured the Proxy mode in FF is set to "No Proxy". I do not have any extensions running or themes.

I am at a complete loss at what setting in FF I need to change to restore this functionality.

Thanks, Matt

Hi, Nvidia RTX Video HDR and Super Resolution works fine when I open a link. But if I scroll the page it turn off. The video still play but the colors changes, I can see that RTX enhencement is then inactive on the nvidia panel. Sometime immediately sometimes after more scrolling. Same on Youtube and Twitch. Any Idea ?

As the subject says Firefox very suddenly started giving me terrible loading times, despite all the sites working perfectly fine on other devices and browsers. Issue continued with troubleshooting mode, not sure where to go from here. I will open youtube, it won't load about 5 thumbnails, I click on a video and it sets it to 140p and then it still lags the entire video as if I was using 1kbps internet. I tested my wifi connection and its having no problems. Something similar happened when I used to use Opera GX, it was fine for a long time and then one day terrible performance. Please let me know where to go from here. Windows 11 Pro.

Regarding the current state of Firefox and WebUSB, I have four thoughts:

1. Yes, Mozilla's concerns regarding the security risks are valid, but not insurmountable.
2. In my experience, this is the single W3C noncompliance that impedes my use of Firefox.
3. In my experience, an increasing number of companies/organizations are leveraging WebUSB, from core-functionality of end-user hardware to enterprise-level troubleshooting, configuration, and support.
4. If Mozilla permits the use of unsigned plugins for its Firefox Developer Edition because of the reasonable expectation that its users understand the risks, it stands to reason that the same could be said for WebUSB.

(There's no need to reply, really - this is only being publicly posted because there doesn't seem to be a way to do otherwise - I just wanted to go through the exercise of casting this message-in-a-bottle into the sea.)

Recently starting having the issue where some whites and the tab icons appear washed out and even glitched out and pink when using my PC. I haven't made any significant changes to my system as far as I recall.

Colours in other browsers and applications are effected. Going to the same webpage on both Brave and Edge shows the whites correctly. On all the games on my PC there are no glitches in colours.

I have tried a few fixes already: -Removing and re-downloading GPU drivers - Fixes the issue temporarily. After about 1 day the issue comes back. -Re-seating the GPU - No fix. -Turning off colour override in Firefox - No fix. -Uninstalling and reinstalling Firefox - No fix.

If anyone has an idea or knows the setting that may be causing this problem I would really appreciate it.
