Diễn đàn hỗ trợ Firefox

My Firefox Web Browser has been consistently every day crashing regardless of how many pages or tabs have been open. Regardless if I'm actively using Firefox when it crashes or leaving it up to do something on my phone. These crashes started shortly after Firefox had that major structural update, but recently Windows 10 had an update it forced me into. I don't know if either is the cause. What happens before crashing is the page goes either all black or all white and then all tabs are gone. This wouldn't bother me so much if Firefox crashing didn't interfere with my AdBlocker and make me reload everything for AdBlocker. I have tried updating Firefox and troubleshooting Firefox and not opening so many tabs -- and nothing helps. I want Firefox to stop crashing and find out what the problem is. Please help!

This is what I have for the long Report ID number(s:): bp-fd4ea624-e71b-4d83-9dc5-4068c0210622 6/22/2021, 5:15 AM bp-ca2334c1-ac45-4c10-bcd5-eca360210622 6/22/2021, 5:15 AM bp-189f0e5e-25e6-44dc-bf62-fa0320210622 6/22/2021, 5:15 AM bp-20fdf0ed-dd26-4a5d-b912-7a5010210622 6/22/2021, 5:15 AM bp-e8e1529b-c10a-47b9-844f-6d5d20210622 6/22/2021, 5:15 AM bp-ce5a0e39-4c4c-465e-b85d-c88fa0210622 6/22/2021, 5:15 AM bp-f653c127-b5dc-44e2-b13a-b11c70210622 6/22/2021, 5:15 AM bp-ed4f9869-7069-45ed-9ce4-a560e0210622 6/22/2021, 5:15 AM bp-12ea0d64-1640-4eab-b0cc-3cad90210622 6/22/2021, 5:15 AM bp-bc9b7bcb-a06c-4a53-8ed8-22fb80210622 6/22/2021, 5:15 AM

Dear all, when in type the address and "enter" the page don't charge. I have uninstalled Firefox and reinstalled it, but the issue persists. I can't even open the Firefox settings. ESET Internet Security confirm that everything is ok. Any suggestions for trouble shooting ? Thank you in advance for your responses.

Since the 89.0.1 update on Windows 10 21H1 (Build 19043.1055), Firefox will not let my PC sleep, unless I quit and re-open Firefox. There is no audio playing on any tabs, but after a while of using Firefox on YouTube or whatnot, it will not release the audio device to let Windows put my monitors to sleep even though all playback has ended.

This can clearly be seen by running "powercfg /requests" as an administrator.

With videos playing, as expected Firefox reserves the audio device, as well as an Execution request.

Output: [ PS C:\WINDOWS\system32> powercfg /requests DISPLAY: [PROCESS] \Device\HarddiskVolume6\Program Files\Mozilla Firefox\firefox.exe display request

SYSTEM: [DRIVER] High Definition Audio Device (HDAUDIO\FUNC_01&VEN_10EC&DEV_0900&SUBSYS_10438581&REV_1000\4&2d156fef&0&0001) An audio stream is currently in use.

AWAYMODE: None.

EXECUTION: [PROCESS] \Device\HarddiskVolume6\Program Files\Mozilla Firefox\firefox.exe non-display request

PERFBOOST: None.

ACTIVELOCKSCREEN: None. ]

But after you stop playing the video the output becomes: [ PS C:\WINDOWS\system32> powercfg /requests DISPLAY: [PROCESS] \Device\HarddiskVolume6\Program Files\Mozilla Firefox\firefox.exe display request

SYSTEM: [DRIVER] High Definition Audio Device (HDAUDIO\FUNC_01&VEN_10EC&DEV_0900&SUBSYS_10438581&REV_1000\4&2d156fef&0&0001) An audio stream is currently in use.

AWAYMODE: None.

EXECUTION: None.

PERFBOOST: None.

ACTIVELOCKSCREEN: None. ]

You can see the audio device doesn't get released, and the only resolution is to quit and restart Firefox.

This doesn't always happen, but does happen after a while.

Loading external website in an iframe is getting blocked because of x-frame-options in response headers. I want to detect what is the value for x-frame-options and based on that value i want to show an alert to the user. How can we detect/extract x-frame-options from the response headers for the given url even if it has redirects?

The feature "forget site" is commonly used for solve site caching problems, however this clean saved passwords too, but it is a problem for me. I'd like a configuration option to avoid this.

Trato de entrar a la página de American Express, pero en primera le cambia la tipografía a una horrible, y luego trato de loggearme y se queda en blanco la página, ya intenté en modo resolución de problemas y también cambié la tipografía y ni una ni la otra se han corregido.

En pocas palabras intenté todo lo que viene aquí y nada: https://support.mozilla.org/en-US/questions/1316294 ________________________________________________________________ I've been trying to enter the AMEX site, but in first place, it changes the typography, and then i try to log in but the page stays in white, i've tried problem solving mode and also changed typography and either have been corrected.

In a few words, i've tried everything from this topic and nothing: https://support.mozilla.org/en-US/questions/1316294

If an item is sent to the Printer, the whole page will appear in the upper left-hand part of the paper with the font so small, it is barely readable?? A similar question has been asked before but the workaround, switch, fix was not evident or workable. I have already checked the Printer settings and it appears that there is nothing in the machine that can be changed. Does anybody have any idea of what is going on here ? There is no memory of anything previously being changed Re: printing page format--it just started for no apparent reason.

I'm a longtime Chrome user trying to move away from that browser. I recently downloaded Firefox and it worked fine for a few days, but now I'm having problems.

I keep Gmail and Google Classroom open in tabs throughout the day (I'm a teacher). They worked fine in Firefox for a few days, but now both sites constantly load or time out.

The problem seems to go away anytime I restart Firefox, but I can't constantly be restarting Firefox all day long. Why do the sites work for a few minutes and then stop working a few minutes after restarting?

I had AdBlocker Ultimate enabled before, but my friend uses uBlock so I tried changing. No help.

I had a theme installed from the recommended list. I thought that might be a problem, so I went back to the default Firefox theme. No help.

What I'm running: Firefox 89.0.1 MacOS Catalina

For the past few days I have been having problems accessing google services. Sometimes gmail will load for me but then later on I will get this message "The site at https://mail.google.com/mail/u/0/#inbox has experienced a network protocol violation that cannot be repaired. The page you are trying to view cannot be shown because an error in the data transmission was detected." After which it is impossible for me to access gmail.

Furthermore, google search also will not work for me. I cannot search from the address bar or when I go to the google website. As well as this I cannot search on YouTube.

I have tried clearing my cookies and cache multiple times as suggested by most posts. This has not fixed the issue.

Any help would be much appreciated as I use these websites very often and this is really an issue for me.

See attached screenshot - I get error message when I try to use OR reinstall Firefox. Suspect Win10 recent updates. The Task Manager thinks everything is fine. Thanks, Joe

I did a refresh yesterday after Firefox had been so slow and now I have other major issues! the letters are not uniform or the coloring on letters are dark and light. I have had this problem in the past and was told how to fix it but that is not working. Told to go to General/Performance/Use hardware acceleration, remove check mark which I have done twice and it didn't help, everything still the same so it makes it hard to read when each individual letter has a dark and light side, r/l or top/bottom! This has been a problem for a long time, especially after I refresh! Two other MAJOR problems though, there is no "HOME" button anymore, and my bookmarks, and bookmark toolbar/menu that I had on the left side of the screen is GONE! Both of those are the worst, and I can find nothing to restore either of them!!!!!! I've used FIREFOX for years, but I get tired of having to figure out how to use it all over again when it slows down or has problems! HELP!

Since some time, Firefox (currently 89.0) on Windows 10 automatically reduces the window size from "fullscreen" to "maximized" when re-opening it from another program. So I have to wait until the window size reduction is complete before having to re-enlarge it again (which is quite annoying)

After a short web search, it turned out that this window size reduction is caused by the "xulstore.json" file in the profile folder and several other users are also reporting this issue. However, none of them in the forums I visited knew a permanent solution. I unsuccessfully tried the following:

• When I delete "xulstore.json", the window size reduction problem goes away only to re-appear after a few re-openings of Firefox (as the xulstore file is re-established then).
• Editing the xulstore file did not work, as Firefox overwrites it.
• Denying Firefox writing permission (via Windows) also doesn't work, as Firefox creates a temporary copy of the xulstore file which again causes the resizing problem.
• Denying access to this temporary copy does not work either.

It seems like Firefox does everything possible just to keep the resizing problem persisting. Is there any permanent solution (different from the failed solution attempts above)? Or even better: could you remove the automatic resizing in a coming version update of Firefox? It seems like I am not the only one who would be grateful about this.

Firefox is only allowing me to paste in plain text—if I copy rich text and paste into Gmail, Docs, or anywhere else that supports rich text, I only get plain text. Chrome handles the same copied text correctly.

This has been an issue of mine for the past few days and I can't find a fix. I've tried to troubleshoot it and I've repeatedly reinstalled Firefox several times. The application either:

a. Doesn't open at all after I click the icon b. Freezes, refuses to register inputs and/or crashes c. Works temporarily, eventually turns into part B

My OS is Windows 10 and I want Firefox to be my default browser but it's not running properly at all on my computer. I have sent multiple crash reports because of this. Does anyone know what the problem could be? This has never happened to me before.

Firefox is very slow on startup also it doesn't allow me to type on the address bar just after startup have to open another window. While i double click on the ff icon it just doesn't open immediately instead a dialog box opens and then 2 windows open after like forever. I have tried the basic troubleshooting ; restarting, clearing startup cache, running troubleshooting mode, disabling extensions etc the problem still persists. Other browsers don't have this issue.

Hi, My questions: 1. How can I make operative a non working older Firefox installation so I do not loose any logins and bookmarks? 2.If that is not possible, how can I find out what is the older profile? I checked and I have three, all with the date of the new installation, no the older one, I do not know how to find the older one OS: W10, laptop installed. Some weeks ago, Firefox did not load anymore (nor Thunderbird and all the laptop windows were constantly freezing) it did not open at all. It has Bitdefender installed, did not find any infection but I am suspicious it might have some. Anyway, I cannot give you the release number because it is not accessible. I downloaded a new update and installation and installed it. Now I have two icons, but the new installation did not update the previous one and did not transfer logings, bookmarks and the like. The non working Firefox is installed on "C:\Program Files\Mozilla Firefox\firefox.exe" The current working one is a 89.0.1 (64-bit) installed on "C:\Users\ username\AppData\Local\Mozilla Firefox\firefox.exe

Thank you very much, Mer

Problems that I faced: 1. There is no firefox window opened, but "new staff train - google drive" window name still appear. Please see attachments. ( the "new staff train" was a window that was closed long time ago) 2. Normally, when one minimises a window and clicks the firefox, the minimize window will pop up, but now it won't.

I did try to delete, uninstall and reinstall firefox, but the problem still exists. Please advise what I can do to solve this inconvenience. Currently, I'm using Firefox 89.0
