Firefox Support Forum

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

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

Hello,

I would like to set different themes for 2 computers signed into my Firefox Sync account, because I would like Firefox to fit in with each system's theme. Would it be possible to do this? If so, how can I set it up?

Thank you, JetFox

Hello,

Am using Mozilla Firefox installed via flatpak on openSUSE. Certain pdfs display correctly but other pdfs displayed with Firefox (either locally or online) are displayed badly: spaces are replaced with a lower half block character, fonts not sharp. I installed Firefox from the openSUSE repos (not from flathub) and opened the same pdf and it displayed correctly. I downloaded the pdf and opened it using Okular and no problems. I also opened the “troublesome” pdfs on Firefox in Windows and it displays correctly. I conclude that the flatpak version of Firefox is causing some pdfs to display incorrectly but I don’t know why.

I installed flatseal to tweak the flatpak Firefox’s settings but nothing seemed to fix the pdf display issue. Please see screenshot below of how Firefox (from openSUSE repos, on the left hand side) and Firefox (from flathub, on the right hand side) display the same pdf from the internet. The online pdf in the screenshot and used as an example of the issue can be found at:

https://www.jrf.org.uk/sites/default/files/jrf/files-research/international_cities_rotterdam.pdf

Not sure why some pdfs display correctly in Firefox from flathub and others display incorrectly. I’d prefer to use flatpak’s sandboxed Firefox if possible. Is there anyone else with the same problem or someone who who found a solution to this issue?

Thanks

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?

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.

As many others have said (however those posts are locked so i cannot reply) Firefox seems to randomly lose the ability to save shortcuts, (by dragging from the address bar) to the desktop.

Restart a few times, wait, random things, and it comes back next time you try... been bugging me for years. Seems to occur when firefox has been running for some time with lots of tabs open. As others have said, it displays a little "NO" icon (circle with a line through it) when trying to drag the URL from the lock or favicon section of the address bar, to the desktop. Other times it works fine.

I searched a bit, but perhaps someone has another idea on how to fix this permanently, or how to recover from it without restarting the computer. Firefox version is 110.0.1.

PS. I would re think the idea of archiving posts. Because its nice to be able to reply to old posts, even if they are "solved". The original poster may have found a solution and never posted about it, for instance.

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.

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..

Hi,

I'm trying to configure equipment on my local network. Some of the equipment does NOT support https. Firefox continuously changes the address http://192.168.xxx.xxx to https://192.168.xxx.xxx, and the connection fails!

I have tried the various options in HTTP Only Mode, including entering Exceptions. I have also temporarily changed network.trr.mode from 5 to 1 (and 0), but nothing is working!

What can I do?

Thanking you Pedro

Network Protocol Error

An error occurred during a connection to www.facebook.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem. I get this often

When I switch from one tab to another doesn't matter the webpage the page adjusts the content on the tab. For example I was on youtube and switched over to gmail and it adjusted the screen and when I switched back to youtube it did the same on youtube. I wasn't zoomed in or anything. I was just on the tab and it was fine and looked how it should but as soon as I switch to another tab it does it on that tab and then will do it again when I switch back to the tab I was on originally on. I'm on FF vers 113.0.2 (64-bit).

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.

Hello team, hope you're doing well. I purchased a new laptop recently(HP Omen 16 with RTX 3070Ti). I installed Kali OS via VMware, which runs on my host machine(Windows 11).

Everything seems to be working fine in Kali, except when I try to play any video via Firefox Browser, it lags a lot and is very choppy. At first, I thought it was the issue with Kali hence, I reinstalled Kali and tried again. The issue still persists. I then did a clean Windows 11 install and tried everything again right after Win11 was set up, but I still couldn't find a solution. Tried all the methods which I could find online, but still, nothing worked.

I tried again, but this time with Windows 10 Pro on VMware. The issue was resolved and everything worked perfectly fine when videos were played on Microsoft Edge.

I've installed the Firefox browser on my host machine, and everything runs smoothly on my host machine(Windows 11), but the issue occurs only when videos are being played in the Firefox browser via Kali on Vmware/VirtualBox. I had asked many known people, but none of them have ever faced this issue with Firefox to date. Neither did I with my previous laptops. This is the first time something like this has occurred.

Issue: Any Video, from any site, when being played in Firefox Browser via Kali OS in Vmware/VirtualBox lags a lot and it is super slow(even when the video speed is set to normal). The audio that comes out from each video is like a robotic voice and it is super slow and laggy.

Kindly help and I really hope that we can resolve this issue!!!

I use the closed captions (CC) in YouTube videos with FireFox. Lately I have been seeing videos that seem to misbehave. At the very start of the video, ALL the captions display at once, one after the other. Then, as play continues there are no more captions. Most videos still show captions normally, that is, captions appearing only when the dialog matches them. But a few videos misbehave by showing all the captions at once. Here is one such video.

https://www.youtube.com/watch?v=ZgqJ5wQF944

I noticed this misbehavior within the last month and assumed that the video was doing something peculiar with the timing of the captions. But when I use the YouTube Show Transcript option to display the captions and associated timing outside the video, the transcript looks quite reasonable.

One further oddity, if I take that same URL and load the video in a different browser, for example, Chrome, the captions are displayed normally.

I've included a screen shot of the video in YouTube showing all the captions displaying at once.

What is the compatibility using Google Meet with Jamboard / is it fully supported using Firefox? A simple Google Meet video call works fine. But I want to share a Jamboard or Google Doc during a Google Meet session, and it's not working. I tried to follow the instructions on this link: https://support.google.com/meet/answer/10540294 That is, I opened the Jamboard and looked for the Meet icon at the top, but it wasn't there. When I tried the same thing using the Chrome browser, the Meet icon was there and I had no problem sharing the Jamboard during the meeting.

I would prefer to continue using Firefox browser, but will have to switch to Chrome if the problem persists. FYI - I am using a Mac

Starting with Firefox 113 (on Debian Linux), every few days Yahoo mail stops working properly: I can read emails but hitting any action of them, like Reply, Move, Delete, does nothing at all.

I need to clear cookies to get this operational again. This doesn't happen on chrome on the same computer.

The only add on I have is an adblocker, disabled for yahoo mail. This problem also happens with enhanced tracker protection turned off.

I have been using Firefox 52.9.0, and I know it is outdated but it still synced until a few days ago at least. Then the other day I updated my password to strengthen security. After that, I am unable to sync anymore. Is there a way to fix it? I need to continue to use Firefox 52.9.0. Please note that I do not need to be told about security issues as I am aware of them well enough.

I get the following message when I try to make Firefox to sync:

> Blocked by Content Security Policy

> This page has a content security policy that prevents it from being loaded in this way.

> Firefox prevented this page from loading in this way because the page has a content security policy > that disallows it.

Thank you.
