Firefox Support Forum

I'm not sure when it happened, but somewhere along the line, Firefox stopped showing on-hover tooltips on unfocused windows. Clicking into the Firefox window again can disrupt what I'm doing in another window, however. For example trying to hover on the Firefox window with my mouse cursor, and type the text of the tooltip into a different window, while leaving the tooltip visible. Wrecks that idea!

I guess I assumed it'd be a temporary issue, that'd get resolved in a later update, without having to say anything about it, and I was wrong about that.

Any idea what's up, and how to get the tooltips to work as I would like them to?

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

Why can't Firefox copy text to the clipboard anymore? It won't copy text from a web page, from a URL, or even from about:support "Copy text to clipboard"!!! I'm using version 1.22 64 bit on windows 11. I've reinstalled Firefox but it doesn't make a difference. I've tried "Troubleshoot Mode" and it's still broken!!!

I can paste into Firefox but something has broken copy!

Stop tabs from automatically refreshing to top of page. Many people have this problem and I don't find a fix. One article states to go to Options and "Warn me when websites try to redirect or reload the page," but I can't find options.

hello ppl i hope u guys doing good look in some sites firefox is not playing any sound no audio like on facebook reels or watching a vedio there i cant hear anything and some sites also when i watch vedio i cant hear any sound but in other browser everything work perfect but i like to use firefox its audio prblm and pls know thats the prblm is not from my windows i have windows 10 everything work fine pls help me fix this thx.

I started getting this message today - "this page is slowing down firefox. To speed up your browser stop this page" How can I fix it other than to start using Safari.

I often like to have 2 browser windows open with multiple tabs going on each window. Recently, however I noticed that whenever I watch a video in full screen mode on one monitor then I switch focus to the second browser window to do other various activities, the video playing on the other monitor will sometimes exit out of full screen mode and continue playing in the original embedded small screen size. So far I've tried disabling all but the most essential extensions, put the theme back to the default mode, made sure my graphics card is fully updated, and even attempted a few setting changes people have recommended for fixing similar issues, but nothing seems to work.

As of right now, the only workaround would be to use the picture in a picture mode and put that to full screen, but that isn't ideal as picture in picture mode is set to be "always on top". I could also use a different browser, like Chome on my second monitor which doesn't seem to cause the video to exit full screen mode, but again, I typically prefer to use firefox for most things online.

Anyway, I'm now out of ideas on what to try to get firefox to behave in the way I want it to.

Here is screen shot:

My iMac is OSX. I use Firefox browser most of the time. I had used Safari years ago. Chrome had rarely been used. Firefox problems recently began. Please help.

For the last few days the ebay website is very slow when I open it. If I switch to Chrome, ebay's website loads okay. All other websites seem to load through Firefox with no problem. Any ideas???

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

Hi Firefox Team, I am a university student, and I keep getting these messages below, especially when I am doing research for my assignments; it is painful as time is of the essence. I need your help asap. I have already cleared my cache, and cookies Thank you The connection was reset

The connection to the server was reset while the page was loading.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If a firewall or proxy protects your computer or network, make sure that Firefox is permitted to access the web.

For the past few days, when I try to log on to PlayStation on Firefox, the sign-in page sits on a loading swirl after inputting email. There's a clear memory leak shown on Task Manager. The menu bar's right-click doesn't draw properly. FF can't be closed and needs to be terminated. The only extension I have is uBlock Origin disabled for this site.

This website works on Edge.

Attached is the broken menu from right-clicking the menu bar.

For 8 months i am still getting tab crashed messages whenever i try to pause then replay videos. I have sent crash reports and shown them on the help page and get no real answers.

I've used FF for years and always had - "Open links in tabs instead of new windows" and "When you open a link, image or media in a new tab, switch to it immediately."

Until very recently this worked well.... now there are two identical tabs opening the link and the switch to immediately does not work.

As of 21/11/2023, I can no longer use several chat services that had previously worked on Firefox, for example Santander bank and EDF. Plus, the POWR widget has stopped working on one of my favourite websites.... it used to pull in the charity's Facebook content but now all I see is the text and no imagery. All of these functionalities work fine in Google Chrome and Edge so what's wrong please? Thanks in advance UF https://www.aldingbournetrust.org/make.html
