Firefox Support Forum

Hi I have been using Firefox for the longest time and never had any issues, recently whenever I try to open the browser it crashes, I am currently using an early 2011 MacBook Pro, funny thing is all the browsers are crashing apart from the crappy safari. Is my hardware too old?

Pretty please help !!!

When you switch the language in a text field, the focus on that text field is lost and the focus goes to another browser tab. This only happens if at this time a video is playing in mozilla in picture in picture mode with the Always on top option enabled. How to fix it? (Ubuntu 22.04)

The following html inscription animates when clicked (the duck in the image quacks), but for some reason, the animation doesn't activate on http://ord.io with the firefox browser. I wanted to bring this to your attention because It works on http://ord.io with every other browser.

Every time I browse incognito mode and download files (pdf mostly), then I exit the browser and my files disappear from the Downloads folder in Windows 11. It has been like this for a long time now. I have to remember to cut and paste them to another folder before shutting the browser down, but when I forget it's annoying. Can this be fixed?

when I click on links to take me to website through my email in Thunderbird that I will get an error message that reads "we could not verify the certificate, reason=wronghost"

Do you get the error in Thunderbird or in the browser? What browser?

   But, if I copy link and copy into browser it works fine. 

Is that the same browser as the one which opens when you click the link in Thunderbird (a.k.a. your default browser)?

In answer to these questions: I use Chrome or Duck Duck Go. Duck Duck Go is my default browser. If I copy and paste link from email in browser it opens, but if I click on link in email I get the error message above. Also when you reply the email is a do not reply email so I can't reply back. Please include a good email so I can answer any questions you may have. Thank you

Using Mac OSX El Capitan 10.11.6 and Firefox 75.15.0 esr

I have a number of desktops defined in "spaces" and each app goes into one. Something odd has happened with Firefox.

When I select a different Window from the Window dropdown, or from the Dock, sometimes there is a "sliding sideways" effect.

And if I go into Firefox by going to the Dock and tapping its icon - it goes to one window; BUT if go to the Dock and tap again, it changes to another window. I think, always the same two.

So its sort of behaving like "spaces" does, but when I view all the "desktops" in the selection view at the top of the screen, I only see one containing Firefox windows.

Its really annoying when the window changes like that, and I don't know how to get them into a single grouping. I have quit & reopened many times, but it persists.

If I knew which of the Firefox Windows were in each of these glitchy "pseudo-groups" then I might quit all of one group, and then re-open them. Not sure if there are just two such pseudo-groups, or more.

Not sure which is the cause. On multiple laptops and desktops after last Windows 11 update and then an immediate Firefox update, the software protection service of Windows 11 goes into high cpu mode consuming 40-50% of cpu when Firefox is opened. Running Firefox version 122.0 (64-bit) version. Tried in safe mode and still having issue. Just an FYI for developers to look into for next Firefox update.

here is the latest of many crashes documented. I have no idea how to fix this. The problem-solving measues on the Fierfox website were all without success bp-5ab98827-7fab-4757-8baa-db3360240204

Hi All!

I have a problem with the launch and operation of Mozilla Firefox/Seamonkey. Sometimes the browser gets stuck for minute until the sites start opening. At the same time, when browser starts up, I see activity that was not initiated by me.

After some time of use, the system crashes with a blue screen with an error in the ndis.sys driver.

These problems began to occur after one of the next FireFox updates. Previously, the system had been working without a blue screen for many years. If I do not start FireFox, the error does not recur. Also, if I make filtering TCP connections with the site in the RU zone at the external firewall, FireFox works stably.

I want to understand which process/component/setup entry initiates this activity. Also, I don't want the browser to try to get any information from sites in the RU zone.

FireFox version: 115.7.0esr (64-bit) System version: Windows 7 Pro 64-bit SP1

Thank you!

Dear Team,

Since one day my tabs crash, in the beginning it was only once per hour, by now it happens every 0.5 seconds. Crash report id: bp-85d2c8d1-94f7-4fd9-bc8b-a1d480240209 I reinstalled the newest version and I tried starting in troubleshoot mode but crashes still happened the same way.

Update: Restarting my computer fixed it :'D

Hello, I have been looking at my traffic and discovered that my firefox for some reason does multiple DNS queries for the same domain, usually 6 times or 3 times, why is that happening I have checked with chrome and it does only 1 request per domain name.

I have attached a wireshark dump, the response is there instantly in very few ms yet it keeps querying the same name again.

My version is 115.3.1esr (64-bit) I have checked in about:config with dns and couldnt find anything relevant.

Hi,

I have got a problem with Mozzila for like a year or two - most of the time the browser is fast and react imidiatelly, but sometimes when i click on any link it only shows grey loading circle in tab name and took about 8-10sec to stop and not load anything. When i try again, linked website is loaded imidiatelly. This happening like aprox. 4-5 times in an hour of browsing web, but sometimes its all good for few hours. Opening even new tabs doesnt help and they are "stuck" in loading for the same time. Then, after that 7-10secs all of them works fine. (When i open new tab and wrote something when it is "stuck" and then when it unstuck then it deletes all what i have typed in adress box and whole tab is in default state). When i close and open Mozilla it works fine but again, just for some time (random duration..). Sometimes, it loads like half page (for example, images are missing).. when i reload site after "stuck" then it loads perfectly fine.

Im using pretty decent PC: Ryzen 5 5600X, HyperX 32GB RAM DD4 3200Mhz, Samsung Nvme SSD 3.0 512GB (now changed to WD black Nvme SSD 4.0 1TB), Aorus RTX 3070, ASUS B450-F Gaming MOBO with 1gbit ethernet card, Win 11 Pro.

Got best internet provider in area (almost no outage, like 1 outage in 2years) - got 1Gbit internet speed (Ookla speed test shows 900Mbit+ download and upload, with ping avg. 0,6ms

I am assuimng, that all components are good because when i play online games for hours it never disconnects or lags or anything, same is for downloading stuff, VPN connection etc...

I have tryied yet (was testing with VPN or other stuff off): 1. clear cache/cookies 2. update Windows / drivers / BIOS 3. reinstall Mozzila without loggin in / importing stuff (few tries) 4. reinstall whole PC 2 times (with changing name of PC), 1x try using Mozzila without even logging in (so absolutely clean Mozzila and Win) 5. update router, reset router multiple times 6. set DNS from auto to Google ones (8.8.8.8 and 8.8.4.4.), in router and in PC 7. turn off antivirus and firewall 8. was using many diffrent versions of Mozzila cose it happening like for 1-2years now

Got laptop with same Mozzila acc linked in and synced and there are no problems even in same network / same cable connection

Was trying to google some help or browse your site but there are mostly only common things which I alredy tryied..

Was not using other browser, cose I am used to use Mozzila (suggestions, looks, etc...), so i am trying to avoid solution to change browser...
