I have random Tab crashes in Firefox when running UI tests with TestComplete. TestComplete proviedes a dmp file. After analyzing with WinDbgPreview it provides an error with the xul.dll:

As I use Firefox throughout the day, webpages will just stop for a bit. Sometimes its only a few seconds, other times for a few minutes. It is most noticeable when playing videos but does happen at other times as well. During the halt, I can still access Firefox's settings and all menu items. It is just website interactions that stop.

For example, when a halt occurs on youtube, the video will eventually stop, depending on the buffer, and scrolling through the comments won't pull up any more and replies won't load. Then after a few moments, everything will start working again without issue, and all the uncompleted actions (such as opening new replies or trying to go to another page) will execute.

I used to think it was related to my computer's connection to our company's access server, but refreshing my connection through a CMD ipconfig /renewall worked so rarely that I assume it was just coincidental timing.

I also tried turning off hardware acceleration, but that had no positive effect. I'll make a separate post about that issue.

The thing that fixes it every time is odd: launching Chrome. I wanted to make sure it was just Firefox, so I tried launching Chrome, and then Firefox started working immediately. (Spotify still plays when Firefox halts too)

Is there anything I can adjust to keep this halting from happening? I can manage right now, but it is sort of annoying to launch Chrome every time.

Firefox 117.0.1 Windows 10.0.19045 Build 19045 Unable to download statements on Barclaycard site. Just spent ages with Barclaycard chat who continued to say Firefox does not support pdf even though I said I was downloading on many other sites no problems. On Barclaycard site I did a transaction search and downloaded the result as a pdf OK. pdf downloads open directly in Adobe reader. Trying to download a statement does nothing, no error, just nothing. Microsoft Edge works ok. Been using Firefox for years on this site no problem. A latest Firefox update problem?

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

Hello everyone,

to archieve some good old games, I use an special version of Firefox. Firefox (MyPal): 29.2.0, with Adobe Flash preinstalled, Disk-Cache

For most games it will suffice: After loading all content online, it will be available offline too. But... some audio/video files will be saved in memory cache - %temp%\mozilla-temp-files\*[random-auffix] - instead of in disk cache. After closing session they get deleted and after restart they are saved again, with another suffix.

Sample file: http://arcaneonlinegame.epizy.com/Arcane/frames_files/midi/Ophelia's Journal.mp3 that is shipped with http://arcaneonlinegame.epizy.com/Arcane/Arcane.htm

How can I tell Firefox to permanent save streamed audio/video files, like Firefox does with everything else? In the end the music should play if I open the browser offline too.

Thank you in advance for your help. Drago

I use two monitors, and I have multiple firefox windows open at once. When I turn on my pc and open firefox, the windows almost randomly position themselves on both monitors, sometimes they are not maximised either. How can I change this behavior so that all my firefox windows open, maximised, on one monitor rather than both?

My Firefox tab crashes often. I eventually need to reboot Firefox. My Windows 11 patches is always up to date and I did system checkups often. I cleared cache files too.

Your Firefox profile cannot be loaded. It may be missing or inaccessible

on debian 12 linux

I tried `firefox` `firefox-esr` `thunderbird``firefox -P`. I also deleted `~/.mozilla`, `firefox -p presaved-profile-dir` stay the same.

the `firefox binary` and the `profile dir` are all useful because I saved them to zip file and use them every day. So is there any other dir besides the 2 dir which fails the startup? even thunderbird fail with the same reason.

Help please, thanks!

Hi I am running latest firefox on windows 10. After a google search I have to put the view to full screen or move the window to see all the options on the right like 'tools' which I use a lot to limit to UK and the last year. is there any way to notice the window isn;t full size and the optios display should be made smaller or put into 2 lines?

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

I have a number of pinned tabs, which occupy a lot of space.

I'm looking for something like a drop down menu to the left of the tab bar for only pinned tabs, which would then eliminate there display on the tab bar. Kinda like a pinned tab bookmark button.

I'd prefer it on the tab bar, but I guess a toolbar button would do.

I'm trying to restore Firefox Bookmarks and stored login/passwords from a Time Machine backup of my Macbook Pro. I've read in the Mozilla support articles where this info is stored, but my backups have no Firefox folder under "Applications Support." Did it get eliminated when I signed up with Mozilla in order to get help with this? These files are on my current system, but they only have a few items that I've entered today.

Since 117(Beta)I have an issue with Firefox refusing to apply the update it downloaded. I've tried searching left and right on the internet for a solution and one does work which is installing the newer version of the browser each time myself. But this is ofcourse not a solution in the long run.

It tries now to apply the update 118b9 to stable version 118 and it did downloaded just fine and asked me if I wanted to close the program to let it update which always worked. I've tried different DNS to see if that could be the problem, tried a clean default profile to see if that helped, I haven't tried uninstalling it and reinstalling it, due to me losing my passwords and what not.

I also tried to run the stable version to see if the issue was still there and it is still there, so me using the beta channel isn't the issue here.

Firefox 117.0.1 (64 bit) Build 20230912013654 Windows 10 Home - Version 22H2 OS build 19045.3448 The link to download my Sears credit card statement in pdf form has disappeared when accessing the website (https://citiretailservices.citibankonline.com) with Firefox. It still appears and works normally when the website is accessed with Chrome. I have the uBlock Origin extension installed on Firefox, but it is disabled on the Sears website. Screencaps attached.

I have noticed few problems using history with Back and Forward Button.

Firstly whenver we use back button my website to the hiistorical visited website in that same tab. However i have noticed that it keeps forgetting the count or number of historical sites visited in the same tab.

For Eg: if i navigate to several pages on the same site. Firefox will only remember few clicks upto 2-3 back.

Surprisingly when i click back button i am not able to come back to the last visited page by clicking forward button. Once i click back button then i wont be able to come to forward sites as the forward pages are fully lost.

I dont know why is this happening

1. Drop down to select the question. In search engines, when entering text, there is usually a text prompt to choose from, but I cannot select it 2. Verification code issue. The verification code usually swipes to the right after input, but cannot be moved at all! 3. Video acceleration issues. On video websites, it used to be possible to right-click to indicate video fast forward, but now there is no response after operation

My English is not good. Could you please write something simple and easy to operate so that I can translate correctly? Thank you

Hi, folks. I may (or may not) need some help here to quell my confusion. You decide... If we accept the result of a google search for the definition of "word(s) grammatical meaning" (which is stated as "the meaning conveyed in a sentence by word order and other grammatical signals"), then I'd like to offer a suggestion for the grammatical rendering(s) of word(s) as viewed in some of the instructions I've found on Mozilla web pages that would really help me to better understand what the instructions impart.

    I hope you folks will see that I am not being "nit picky" NOR being disparaging towards a person or their use of words, phrases, syntax, etc. in relation to their presentation(s) of examples, solutions, intructions, etc.  It has been & continues to be a challenge for me to understand/comprehend what I read sometimes, due to some limitations I have (still, at age 75 even) which are akin to being dyslexic & having attention deficit hyperactivity disorder (ADHD).  If one does a google search for these maladies, it can be found that potentially millions of people are afflicted.  Depending on the web page visited, one can find varying percentages of the total populations of various geographical locations for these disabilities, which tends to support the notion that we number in the millions.  So, there may be others who might benefit from the suggestion(s) offered here.  If you will accept the notion that I really do appreciate the time & research folks avail themselves to (and then present via the Firefox venue) aimed at the edification of those who would benefit from their selfless actions, then please consider the following, non-dissing, presentation edits...

OK, if my premise (as stated directly above) is within the scope of Firefox verbal etiquette, then I'd like to share some requested changes to descriptions, actions, instructions, etc., that would make it easier & be less time consuming for me (and mayhaps quite a few others) to read & understand (at least) some of the articles presented on Firefox web pages.

As I paged back thru the web sites to find the web page I had visited that gave rise to my concern about understanding what I was reading, it surprised me that it took 10 clicks on web page links to do so. I bookmarked the link to the web page which had the text fill-in box I am currently using, hoping I could avoid my original 10 webpages of links, journey.

OK, here I am on a Moxilla Supprt web page "Back up and restore information in Firefox profiles" with the URL: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles PAGING down to the "Restoring a profile backup" (under the Table of Contents), I can find no reference to the location of the action described in item 1. Click the Firefox menu Button and select Exit. Where do I need to be in the Firefox app. to execute this action? After performing the action described in item 1., am I directed to the Explorer? OR, do I need to open the Explorer? OR open a cmd line prompt? in order to be able to view the two directories referenced?

For the action described in item 2., referencing "existing profile folder" and "profile backup folder", why is "profile" not the middle word in each of these three word combos? AND, if I execute the action referenced in this item, am I replacing the "existing profile folder" with the "profile backup" file (located inside the "profile backup folder "?) AND, are there any other files in the "profile backup folder" along with the "profile backup" file?

Also, is this action performed from the Explorer? or a CMD line prompt? AND, if I overwrite my existing profile with my backup profile, then I will lose all data from the existing profile that is not represented in the backup profile. That could be sizeable depending on the amount time elapsed from date when the backup profile was saved to the date the current profile is still in use.

I am further confused by the word usage in the "Important" comment: The "profile folder names" (ostensibly referencing "existing profile folder" and "profile backup folder") must match exactly. Yet the descriptions of these folders do not use the same naming format.

PAGING further down this web page to the next item in the Table of Contents, I find "Restoring to a different location". Is the action in item 1., in this section, the same as the action in item 1., of the section directly above it, "Restoring a profile backup"?

It appears as tho items 3., 4., 5., & 7., in this section, use three different phrases to describe the same entitiy (and/or its location?) i.e., the "backed-up profile folder", the "profile folder backup", & the "backed up profile folder". Are the "backed-up profile folder" referenced in item 3., the "profile folder backup" referenced in item 4., & the "backed up profile folder" all folders (directories & sub-directories)? The naming convention here is uber confusing....

AND now, so am I (confused). BUT, if I am the only one, then please ignore my ramblings above. I will take no more of your valuable time. NOR, will I need a response. With some "trial & error" scenarios (and the time to execute them), I am sure I can figure this out.

Uno, a thot does occur to me. Am I even in the right venue here to find out how to save/backup my emails stored with my online email provider? After re-reading the Firefox online support for backing up Firefox profiles, I did not come across any nomenclature identifying any emails. I mean afterall, that is what I'd like to do & reduce my burgeoning signature (footprint?) of thousands of stored online emails... SO, are emails stored in the "backed-up profile folder"? AND if so, are they one of the files in this folder? OR, are they a part of the "backed-up profile" file? (I mean if there is such a file...)

P.S... Here's a comforting tid bit of info. By cutting & pasting the URL (that I saved & briefly texted about earler) which opens the web page with this text fill-in box, I circumvented needing to select 10 different links to get here...
