I-Firefox Isithangami Sokwesekwa

Hi all ,

i have one website which downloads the content (image/video/html) and save in localStorage also i have service worker who fetches those files.

while downloading the files from one url lets assume ( download.files.com) firefox downloads correctly , but when my service worker tries to fetch the html file from its own url ( url/content/files/downloadedHtml.html) its gives  404 not found , but when i open same url ( url/content/files/downloadedHtml.html) in second tab its giving 200OK. 

also in network tab it gives me "NS_BINDING_ERROR" .

Everything worked normally for me for 2 years, but recently i decided to reinstall windows. So i did it, downloaded firefox on raw system and now i get this error on some youtube videos. I tried everything i could find but nothing fixed this issue. It pops up with firefox account, without it, in private vindows, in regular ones, with addons, without them. I tried reinstalling firefox, i updated every driver, i use google DNS, but it still doesnt work. In edge, chrome etc. theese videos play fine

I recently got help (thank you, Cor-El!!) and was able to put Firefox into compact mode. It's still not enough. Is there anyway to make even compact mode smaller? After websites add their own headers and all, it now leaves me about 2 inches of working space; it's better than one inch but isn't enough to see things.

I've been trying to keep going back to version 99 (darker attached screenshot in blues) but it isn't being allowed. The other screenshot (lighter, in oranges and pinks) is the current version in compact mode. It's a bit better, but still is not good.

Is there any way I can change the height of the headers myself? Or can I ask someone else to do it? I'd like it about half to 2/3 the size it is now, even in compact mode. Can I do that? If so, how?

Or, can I switch things around so the headers are at the side of the screen? This is a standard 15" diagonal screen laptop currently running Windows 10.

I have one Firefox profile with work and personal stuff, and am creating another profile just for work. I have exported the passwords from the first profile and deleted all my personal ones, so the Excel file just have personal passwords. I am looking for a way to import this file into my new Firefox profile. I see how to do that from another browser, but not from a file or another Firefox profile. Any help would be appreciated.

Firefox is Generating Error Messages. I use a password manager and know the correct ID and Password is being used. Twice recently, I have had to resort to Microsoft Edge to get around denial of access by Firefox. What do I need to do with Firefox to eliminate the denial of access of a website?

Recently something changed. Used to be that opening a tab presented a horizontal mid-screen array of icons of URLs. Handy. Don't know the lingo. They've been transgraded. Be nice to get them back.

Windows 10 desktop. Latest Firefox..

I saw an other article about the same possible but they had a problem with an extension but I dont have that extension but still have the same problem. Whenever i watch twitch or youtube and i alt tab or switch tabs my audio and video stops playing.

some websites load in private but not normal browser. i have tried in safe mode with no addons still no luck, ive tried a few odd and end things to get these sites to load with no luck. any advice would be great. i do not get any errors the websites just stop loading or playing videos.

hello team,

i have a question about feature in firefox, that is auto sleep tab. that's what i call it.

let me tell you first to get better understanding. so i'm work as a vendor for my client. and to connect to my client environment, usually i used remote desktop connection. there is firefox too but a little bit different. in remote desktop firefox, there is a feature auto sleep tab. so tab that hasn't been accessed in a few minutes will going to sleep state. but it's different with my local firefox. no matter how long I do not open the tab, it never goes to sleep state. i'm pretty sure i'm using latest version and same type of firefox. but why that feature doesn't exist in my firefox?

Long story short I've lost about 30-40 tabs and can't get them back. What happened was that my computer was being strangely slow, so I opened task manager to close some stuff with one of them being firefox. I had about 6 windows open, 2 of them having a lot of tabs, the other 4 only having a few. Reopened firefox, click restore previous session and only 3 windows reopen. I've never had this before and am scrambling to try to fix it as the tabs/windows that did not reopen are the ones that were actually important. I've tried to use the scrounger thing that jscher2000 has suggested and haven't been able to find anything (I don't know much about code tho so could probably be missing something). I don't know what to do and am panicking a little as like I said, those windows that did not reopen were important. I'm trying to figure out if firefox saves older versions of the session restore .jsonlz4 files (besides the .baklz4) but they seem to just be overridden/deleted. Is there anything I can do or am I just screwed? Also recently closed windows and tabs options are empty when looking at the history tab, which has also never happened. New update today so could it be that that has caused this problem? Finally, I've looked at the Import and Backup -> Restore option, which has worked for me once when something similar happened, and between Saturday morning and now (Tuesday), there is nothing, which is odd as I close out all my tabs every night and this morning everything was restored perfectly. Yesterday is when I opened a lot of the important tabs for the one window, so could there be some kind of glitch occuring there? Any help would be appreciated Thanks

Not noticed before but when I right-click on the Firefox icon in the task bar, it pops up a list of recent browsing addresses, especially the ones that have started off as a i-click, browser tracking or whatever. I didn't think that they should be there as I have selected "always use Private Browsing" and my history is not being saved, or so I thought. These are active links. Clearing history, inc data and cookies doesn't remove these links. Nor does CCleaner or Bitdefender remove these. I want all history and cookies deleted when I exit the Browser. Apart from removing them individually by right-click, what do I do. It seems that Edge does the same on my partners laptop

Dear support, I'd like to ask you about auto-update option enabled in Mozilla Firefox. In our company we have Mozilla Firefox ESR onboarded and in use. One of our security report showed that Firefox version we use across company is vulnerable - because not all machines have the latest version installed. So I was a bit surprised because I know that auto-update is enabled for this application. I've checked it on my machine and I've got the latest version once I open Firefox and check via "About" button, right after that I've got the latest update installed. Together with my colleague we checked it on her machine whether it's really needed to check the version manually and then update is installed or is installed in the background and seems that my colleague got an update without manually checking the version, she just left the app open and after some time we checked the version and it was already updated.

My question is - is it enough to have Firefox open and it installed the latest version in the background without any action needed from user? Or user has to manually check the version and afterwards the update will be installed?

Another question I have, is the application vulnerable even if the app is not open?

Thank you in advance & BR

When watching something on Youtube and I click on the coloured download icon, I get to be able to click on the title of the video. A blue 1 appears in the download icon. When I click again, then click on the blue 1 to watch the download. Nothing happens. The window just sits there and states 'downloading', but it does not happen. This happened last year and you managed to fix it; now Youtube seem to have blocked downloading again. Geoffrey D Dean, Australia.

like the title says, i installed the latest Firefox update and my graphics driver started crashing every few minutes. tried updating my graphics card driver (Nvidia RTX3070) and tried to set the browser to software rendering, but nothing helps, it keeps going black and restart every few minutes.

There really should be a option to revert from a update, i had this a lot with Firefox, troubles after updates. And with no way to fix it, so i have to use another browser until it is fixed..kinda troublesome.

There are many mainstream websites that have stopped functioning in firefox that work perfectly fine when switching over to brave and enabling scripts

these are not obscure sites, they are sites for privacy protecting entities hence the lack of function on firefox is perplexing

how do we make these sites work in firefox again to save the switching to brave?

I would like to add the bookmark tree to my Fickle theme so the colors used can also be seen when looking at my bookmarks. I would gladly ask permission from the person who created the bookmark tree extension and try an see if his extensions could list the bookmarks in the same blue/yellow colors of Fickle. I hope it can work and thanks for any and all help. Rob

Since the task limit option seems to have been obliterated? I believe the many more "programs" and the events they create for windows to handle is causing all sorts of virtual memory problems. Changing win10 advanced system settings from performance for programs to background services seems to have restored Firefox performance in my case, see: 10 advanced system settings win10 advanced system settings performance programs vs background services Is there an about:config option that would allow one to achieve the same "programs" limiting option as before? This laptop has 16 gig of memory and I used to successfully have even better Firefox performance with windows virtual memory turned off, but eventually I would get crashes. I can understand why Firefox was modified in a way to better localize the source of crashes, but in my case it has degraded performance. Thanks Mozilla for a great product I have valued for years!!!!
