when i open site on mozilla its show SSL type Error on this site https://www.rehanrentacar.com but on another browser its working well , so how can we solve on mozilla ?

For the past few weeks (perhaps after updates?), my Firefox browser has refused to connect through AVG secure VPN - it is completely blocked and time-out on ALL websites. When I disconnect the AVG VPN, then Firefox works immediately correctly. It happens on both private and public networks.

Both Firefox and AVG secure VPN are up to date. Firefox 120.0 (64- bit) AVG Secure VPN 5.28.9117 I have been using AVG professional antivirus and firewall for years. Windows 10 Latest Version.

Any suggestions please?

when i am opening any streaming site and play the video, the audio stream of the video sometimes start late and some time does not even start when the audio is played via bluetooth audio device.

Hello dear supports i created a firefox account with my pc and i just have that on my pc not mobile and i just sync all of my info(sync now) and i would change my windows for viruses,now i reinstall firefox and singin in my acc and i dont see my pass,history,bookmarks and etc.pls help me i really need those

I saw there was a fix / workaround for pasting text into WhatsApp on desktop in Firefox, but I used to be able to copy and paste images too and that still doesn't work. It works in the AVG secure browser though. It used to work in Chrome, but I don't want to go to Chrome just to send a picture from my desktop. Is there any workaround or fix in Firefox to copy and paste images into WhatsApp on desktop?

After reinstalling Windows 11 Pro on a newly installed SSD my browser resets location and size to default. Nothing listed here in support or found elsewhere through a web search has made a difference. Also, if I leave Firefox open for an extended period of time so that the browser stays where I put it, and keeps the same size, it will crash. As a test, I had Windows resize the browser to the full monitor, closed it, and when I reopened Firefox it filled the monitor. A second time closed and reopened a few minutes later resets back to default location and size. Everything else (bookmarks, extensions, etc.) remains the same. Nothing has been added or removed since the fresh install.

This is the latest version, 23H2, of Windows 11 Pro, which, btw, was the version I was running before the fresh install of Windows 11 Pro.

How can this be corrected?

Thanks.

I typically download 30 to 40 video files daily of around 5 MB each. The most I can download seems to be 8 files, then I have to select the next 8 to download. Is there a way I can select all 30 files and have them download one at a time in order without having to keep selecting the next file?

I am about to stop using Firefox, because recently, every time it wants to update, it goes right ahead without my say so, and completely voids my entire history. Everything is gone. I have to find all my tabs again, and sign into them all again. Dreadful. I was a faithful user of this web platform, bit this is so inconveniently useless, I cannot continue.

Lately, whenever I click on a file (be it PDF, XLS or whatever), it doesn't open. Instead, I see the relevant app (Acrobat, Excel, or whatever) flashing on the taskbar and I have to click on it to view the downloaded files. Not a big deal, but it used to be different, with the relevant app opening a window with the downloaded files (which makes sense: if I click on it to open - and not download - I want to see it now). Does this happen to you as well? I could not find any option to control this behaviour, and I don't think it is intentional.

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

On the first load of the day FF partially loads a page then freezes that page. Links are dead and can't type into any text field. This will happen with multiple tabs then suddenly everything starts to work with no further issues. Note: the browser does not freeze.

Firefox hangs when I try to maximise the window. If the firefox window is covering half of my screen and I try to maximise by clicking on the window button at the top right, it hangs. I get a message "firefox is not responding, wait or exit." Then I have to select close, and start it again to work. This happens occasionally, once in every 2-3 days.

Dear Support Team,

I always receive popup messages when trying to play a youtube video. "Ablockers not allowed". But I haven´t installed any adblocker. I am not sure, but I think this erreor occurs since the last Firefox update (?). Had never before this error. See file attached (in German).

I am using Windows 10.

Thank you in advance for your help ! Best regards Chris

Hi,

I lost all my bookmarks because I forgot my Firefox account password and didn't realize they were in the cloud (I thought they were stored locally). I don't have any bookmarks backups, but I did recently back up my Macbook via Time Machine. Would Time Machine be able to recover my previous bookmarks? If so, how?

Thank you.

At first Firefox opened and then immediately closed. Then it simply wouldn't open. I uninstalled it. Changed my profile (as per a suggestion in Support I read about). Reinstalled it. It opens now in "safe/troubleshoot" mode for a few moments. I checked the crash report and there are no current crash reports which might help me with the problem. I can't log back in as it keeps closing after I enter username and try to enter password - i don't think its a password issue - it closes all the time even at other places. I'm at my wits end and don't want to abandon Firefox. Any thoughts appreciated. Many thanks, A

Hello,

I have a problem retrieving my favorites/bookmarks. I changed computers (all of them, even the hard drives).

I would like to recover my favorites/bookmarks but cannot do so because I am asked to look for them in folders that I no longer have, because they are on the old computer.

Does Firefox not save any information about my favorites/bookmarks? Have I lost them all? Do I have to redo my whole life?

Sincerely, Shinsengumy

I'm using Firefox 120.0 on an iMac running OS 13.6.1. When browsing in an open window, merely moving my iMouse (no clicking) causes the display to zoom in and enlarge the display a huge amount that is much larger than normal zooming can produce. Please provide a solution.

Firefox has been crashing multiple times per day for several weeks now. It used to be fine, hardly ever crashing. I can't think of anything I'm doing differently since before the crashes started. I can only assume that it started after a specific Firefox update. I do have a lot of windows/tabs open at once, but that was never an issue in the past. Occasionally individual pages will crash, usually several at once. The entire software crashes all at once regularly as well. Sometimes the crash seems to cause other issues, such as my computer hanging up for a bit, or my monitors going blank and the graphics system seeming to reset, before Firefox actually crashes. I don't always get a crash report dialogue when the whole thing crashes.

I keep my Windows and Firefox up to date. I tried turning off hardware acceleration, but I think that might have made it worse so I turned it back on. I cleared the caches (which took well over five minutes), and ran speedyfox a few times. I exit Firefox through File > Exit whenever I need to restart or run other heavy software.
