Diễn đàn hỗ trợ Firefox

Hello, I have been a diehard Firefox user since it was still in Beta. I have been using computers personally since 1994 and professionally since 2004, doing Windows and Linux systems administration. I can and will do whatever (within limits) you need me to do to troubleshoot and resolve this issue, which is otherwise going to cause me to abandon this otherwise excellent browser, perhaps forever. The browser.cache.disk.capacity seems to work, but browser.cache.memory.capacity does not.

Why does firefox not respect the assigned values for browser memory cache (browser.cache.memory.capacity)? Is there anything I can do to limit the memory and processor usage of Firefox and its child processes? Is extension CPU/memory usage constrained by the application values? Is there a way to determine and/or limit the resource usage of extensions?

I have included a number of screenshots documenting its behavior and generated an about:memory report during "normal use". After configuring a number of system variables, I then attempted to determine its resource usage under heavy load.

Open the browser with a couple 2, 3 tabs: ~1GB memory usage Use the browser as "normal" (dozens tabs): ~2GB memory usage Open 100+ tabs from history: The CPU and memory resource usage increases until it consumes all available system resources despite configured values. After killing and restarting the process, the tabs have invisible titles in the extension and browser, and must be closed using Ctrl+W until only a few remain after which the browser can be used normally and again consumes ~1GB.

While I understand "just don't open so many tabs", under some circumstances such as poorly written websites, bugs, etc, even single sites may attempt to claim excessive resources. I sometimes run VMs and such on this machine and in order to retain a responsive system, cannot have applications consuming all of the available resources. I have found one proposed solution that uses an external application, is this the only way?

I am open to allowing Firefox to utilize more of the SSD storage (the 1GB limit was imposed for testing) and would be fine with increased slowness due to disk cache or refetching internetworked resources. However, none of the settings I have changed or attempts I have made appear to be able to limit the memory usage in any way. Additional included screenshots are linked above instead of as attachments due to number. I can share or generate additional reports to assist in troubleshooting.

Thank you! JackD

Until yesterday everything was fine. I was able to complete recaptcha. But when I tried searching something today, I couldn't do it because of the recaptcha. It was stuck on infinite loading. Every website I visited the problem was there. I tried fixing it from the tips I found in the forum here but nothing seems to work. I was frustrated. Then I tried Brave browser and it was working. Please help me fix this problem. Thank you.

Firefox is blocking/preventing me from visiting a website even though it is secure but Firefox does not recognize the certificate issuer. How do I get around this? Thank you.

Hey Gang -- Has anyone else experienced this?

Whenever I'm on NPR's website listening to a radio program, I can't access any other websites on separate tabs or windows. (they simply won't 'load' or even acknowledge any commands)

I find this to be very strange.

If anyone can help with this minor quandary I would be grateful.

Sincerely,

--Art

PS - I am using a PC desktop computer, running Windows 10 and using the latest Firefox version 124.0.2

Hi,

I cannot logon to icloud using Firefox (since 3 days) on my windows pc. It normally works fine

I can logon on using the mobile firefox browser and I can logon using Edge. However, I don't want to use Edge

I use a VPN (including browser extension) but I haven't had a problem before

Thanks

Hello Mozilla Support,

Since 2 upgrades ago, anytime I try to watch a livestream, my browser slows right down and then crashes.

I don't care why its happening, I just want a definitive fix for the issue.

I'm so aggrieved at this happening constantly, if you cannot provide a firm resolution to this issue, i will simply move to another browser.

I've tried your about:config setting restart to false and other fixes but still keeps happening.

I await your reply.

With Regards,

Mark

I've had this problem for a while and it's kept me from actually using the program. At any given time when I try to run the application, it never lasts for more than a couple seconds before it suddenly stops with no warning. Whenever I get these crashes, the Crash Reporter never opens. Because of this issue I can't open it in troubleshooting mode. At this point I have tried fully resetting my PC twice, uninstalling McAfee, had multiple malware scans, and have uninstalled and reinstalled Firefox itself multiple times. I'm really not all that good at operating computers, I just kind of know how to navigate files. I don't know what else to do at this point.

Our office uses a cloud-based database. Mozilla won't allow me to "check" boxes to do database searches for specific things. Google works fine, Edge works fine, but not Mozilla. Any ideas on how to fix this would be appreciated. Thanks!

I can hear NO AUDIO on ANY webpage, when in Firefox. I have gone through all the suggestions on this page: [https://support.mozilla.org/en-US/kb/what-to-do-if-firefox-wont-play-any-...] but still have the problem.

Dear Support Team,

Embed map does not appear anymore, after last update of Firefox browser: http://www.ship.gr/map.html

It appears normally in all other browsers. Thank you and best regards Antony ship@ship.gr

So I enabled push notifications for Google Calendar. Every time there's a notification, Google Calendar ask if I want to enable "Switch to this tab" for their notifications. I accidentally turned it on, then I managed to turn it off. Except it now keep asking me if I want to enable it.

Looking at the settings, the only two options available are "Always ask" and "Yes", with no way of just saying no... why?

Firefox has been white-screen blocking my access to some common websites including CNN, Amazon and possibly others. No error messages, just a blank white screen. This is a sudden change and has never been a problem in the past. Chrome and Firefox on my other computers are not affected. I have cleared caches and deleted all tabs with no change in symptom. I've also checked CPU and memory resources and both appear normal. No sites are being blocked by settings either, though I would expect Firefox to give me a "This site is blocked" message of some kind if that were the case. How do I fix this?

For years I was able to view my credit card statements on the Synchrony Bank website, as recent as last year. Today, I cannot view the statements. When I click on the link I get the blocked symbol. (red circle with a slash through it. I am able to view the statements on another browser, Chrome to be precise. What changed? Can it be remedied?

I use firefox for browse internet, but after some time firefox start randomly crash. After some investigation i noticed in resource monitor that one of firefox processes has commit 100% of my computer memory. After some time that process reach maximum memory that my computer has and firefox crashed. But windows still was open (frozen with no content and windows XP border).

I created a one column spreadsheet with 91 entries in Excel. Then I did a "save as" and choose CSV (comma delimited). One the receiving website, I chose "Browse for file", selected the CSV file I juts created and clicked "Upload". I got an error saying it wasn't a CSV file and could not be uploaded. I tried it again (same file) using Microsoft Edge and it worked just fine. I uninstalled and re-installed Firefox and got the same failure as before. I'm running Windows 10 ver 22H2. I really don't want to use Edge. Is there a fix for this?

Firefox since 102 or 103 has a giant issues with gifs, movies ect after resuming from hibernation. In the Dev mode there are errors like this:

MediaLoadExhaustedCandidates = no any media can be loaded

Invalid URI. Load of media resource %S failed

Why does it happen only in firefox? Even in FF 120 Windows.

I want to delete all my web certs except for the top seven, which cover 99.32% of current web certs. I specifically do NOT want the EU Cyber Resilience Act to have the ability to insert their certs into my root store, enabling their member countries unfettered power to compel acceptance of their certs.

I tried following https://wiki.mozilla.org/CA/Changing_Trust_Settings, but this must be for an earlier version. I don't seem to have an Options/Preferences window. On the other hand I am pretty old & maybe just can't find it....

Any hints on how to do this?
