Firefox-Hilfeforum

On bootup firefox opens a single window which says the following:

Sorry. We’re having trouble getting your pages back." We are having trouble restoring your last browsing session. Select Restore Session to try again.

The restore function succeeds in restoring 6 windows from the prior session, but this notice keeps appearing on every bootup.

Here are a few relevant details from about: config

• browser.sessionstore.max_resumed_crashes (is set to 1)
• browser.sessionstore.resume_from_crash (is set to true)
• No 3rd party third party cleaning software
• Two extensions, tab stash and tree tabs
• There are no entries in about:crash for this event

Have been using Firefox from 2004 with 5-10 open windows which appear on bootup as they existed from the prior session. This is the first occurance of this error. Appreciate your support. Here are a few system details:

1.) 28gb ram 2.) Linux ~ LMDE 5 (Elsie) 3.) Firefox ESR 115.8 (oesr) 64 bit.

Over the past few weeks I've been unable to watch live videos on Firefox on Ubuntu 22.04. I thought it was just an issue with Twitch but I realized the problem also persists on live videos on Youtube and did some troubleshooting which didn't solve the issue. The only solution I was able to find for Ubuntu said to install ffmpeg, which I already had, but I made sure it was upgraded, refreshed Firefox, and still have the issue. Currently I'm on Firefox 121.0 but I've had this issue since before I updated it. I dual boot Ubuntu and Windows and am not having this issue when I boot Windows on the same computer and Firefox profile.

Today when I closed Firefox and reopened it the option to restore previous session was not shown, as a result I have lost half my pinned tabs (I managed to redo the rest from bookmarks) which were vital. I tried going into history but the option was greyed out.

This happened yesterday too but after redoing half my tabs I went to open gmail and it restored all my tabs, I tried the sane today but it failed so am stuck with half my tabs.

Please do not suggest I use synch as I only use one device.

On this page with an Atari emulator, I am unable to use its controls that use the Alt key, such as Alt+P to pause.

It works with another browser, or with a fresh profile.

I've tried disabling add-ons and trying it again, but it fails even after disabling each of them. It also doesn't even work in troubleshooting mode, and that seems kinda odd?

It may be some modified settings in my Firefox profile? Though if it is, I don't know what settings, nor how to fix it. What sorts of settings are retained even in troubleshooting mode?

I installed Firefox-ESR on my Raspberry PI and noticed that I cannot play Udemy videos. After some research I found that the Widevine plugin is missing and the OpenH264 Video Codec is also not installed. Following the instructions from similar issues didn't solve the problem. I ticked off and on the "Play DRM-controlled content" button but this only brings the widevine plugin for a moment and after that it disappears. In the network tab I see no activity when click on this button, i.e. Firefox does not send requests.

Additionally the OpenH264 Video Codec is not installed and never installs.

Any ideas how to solve this?

I have a 'site' that is just files on my hard drive.

I need to click an anchor link such as: <a href="file:///dir1/dir2/dir3/dir4">Store Your Files Here</a> and have Firefox open the folder dir4 with the systems file manager. ( In my case the file manager is Nautilus ) ( Ubuntu 20.04 )

I have seen this: http://kb.mozillazine.org/Links_to_local_pages_do_not_work but it does not describe a scenario that uses the file:/// interface.

It also does not provide any information about how the files will be handled.

I can get the folder link to work currently , but it appears with the: 'Index of file///...' in a browser tab.

Obviously you can not use that for anything useful.

The main goal is to open the folder and be able to use the system file manager to include more content for the site without having to navigate to the folder manually. The folders I want to display are buried many levels down without the possibility of having descriptive names. I have ~121 pages/folders in this arrangement , and each one has content for each page. I would like to add a button on each of the 121 pages that will open each of the pages content folder.

I cannot use firefox. About the third or fourth tab or window I open hangs up, and then all of firefox hangs up. The triggering load can be from bookmarks or a new site. Have rebooted, re-opened: same problem. Have updated everything (including snap), same problem. Uninstalled and re-installed Firefox, same problem. Troubleshooting crashes and will not re-start

Having this issue with Youtube since a few days ago, on version 115.0.2 and 115.0.3, and only for videos encoded in AVC/H264. VP9 and AV1 encoded videos have no trouble buffering, only H264 is affected. Happens with or without adblocker, and on different OS. Cookies cleared, no dice.

Video would load the first 20-40 seconds, then does not buffer at all subsequently once it reaches the end of that portion. I have to skip a few seconds forward for it to load the next 20-40 secs, then it would get stuck again.

I can get around this issue by either lowering resolution to 480p (which looks terribly unwatchable), or turn VP9 streams back on (which does not work correctly on my setup, there's a driver bug that hasn't been fixed).

The sure way, and strange thing, is that AVC/H264 videos load and buffer with absolutely no issue when I'm logged out of my account. Also, works with no issue in Chromium, even while logged in.

Anyone facing this or similar issue recently too? Is it still ongoing for you?

For now one week, I cannot sync my browser using Firefox sync. When checking the logs, I always see :

Sync.Resource WARN GET request to https://sync-788-us-west-2.sync.services.mozilla.com/1.5/208380794/info/collections failed: [Exception... "The connection was refused" nsresult: "0x804b000d (NS_ERROR_CONNECTION_REFUSED)" location: "<unknown>" data: no] No traceback available

I have tested on multiples wifi network and mobile data and still the same error. After checking, it seem that this server is down, and I don't know were to report this.

Is this the right place to report this or is it a thing I can do to fix that ?

Thanks

I am trying to use a <select> tag to display a color selector. So each <option> has a background color to match its displayed text:

```<select id="strokeColor" name="strokeColor" style="width: 10em;">

             <option value="black" style="background: #000000; text: #FFFFFF">
                     black
             </option>

<option value="aqua" style="background: #00FFFF">

                     aqua
             </option>

<option value="blue" style="background: #0000FF">

                     blue
             </option>

<option value="brown" style="background: #A52A2A">

                     brown
             </option>

<option value="gray" style="background: #808080">

                     gray
             </option>

<option value="green" style="background: #00FF00">

                     green
             </option>

<option value="magenta" style="background: #FF00FF">

                     magenta
             </option>

<option value="orange" style="background: #FFA500">

                     orange
             </option>

<option value="purple" style="background: #800080">

                     purple
             </option>

<option value="red" style="background: #FF0000">

                     red
             </option>

<option value="white" style="background: #FFFFFF">

                     white
             </option>

<option value="yellow" style="background: #FFFF00">

                     yellow
             </option>

<option value="#000000" selected="" style="background: #000000">

                     #000000
             </option>
         </select>```

On Chrome this displays as expected:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-25-eebbd5.png

But on Firefox the background colors are ignored:

https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-04-18-22-02-35-bd90ee.png

How can I get Firefox to display the background colors?

Dear Support, I posted my js-library on the hosting https://rombase.ru/o5/olga5/o5.js and copied it to https://leonrom.github.io/o5/olga5/o5.js

I try to connect to it from Blogger, for example: https://olga-5.blogspot.com/2020/02/olga5-shp.html?o5debug=2 and I change the link to the library's hosting in the <head> of my blog.

The Chrome browser works the same way wherever o5.js is located. But Mozilla, when placed on rombase.ru, swears in the console: `The resource at “https://rombase.ru/o5/olga5/o5.js” was blocked by Safe Browsing`

My Firefox is 109.0.1 (64 bit) under MX Linux

Could you please tell me: what is the "safety"-difference between rombase.ru and leonrom.github.io? What shall I change in rombase.ru to work properly?

Thank you PS Connecting via VPN (from Ukraine) does not help

What could be causing this to happen on many media files? Version 102.0 in Fedora 36 workstation. This is in a demonstration video about a Travel Trailer shower door installation on this page. Down the page in the reviews section. This happens on other sites also.

Thanks for any help in advance. Bob.

Ark extracted Version 119 files into /home/Downloads/Firefox/Firefox. I tried ./update from the BASH command line, but didn't know which argument(s) to add to that command. I'm hoping to update Firefox 78.14 ESR to a recent version, whether ESR or not. Thanks for your help.

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

I have a Firefox account in order to use the sync capabilities. After a sync between desktop and phone the desktop bookmarks are on my phone in an extra folder "desktop bookmarks" and vice versa the phone bookmarks are in folder "Mobile bookmarks" in my desktop Firefox. Is this normal behaviour? I would expect them in one common folder to have a seamless synching.

Best regards, Walter

Firefox consumes a lot of processor time in background. How to disable it?

Following options do nothing: Use recommended performance settings - dasabled Use hardware acceleration when available - disabled browser.tabs.remote.autostart = false

For several years now Firefox keeps the methodology to update in the background and then force the user to restart.

This always causes some loss.

There are multiple situations where this is not acceptable. Just to give one example: I just logged in an account and clicked to receive an authentication SMS. But then Firefox forced restart and I cannot login nor ask for a new SMS because the previous request was recent.

In my opinion this makes absolutely no sense. Is there an option the turn off this forced restart?

Why does FireFox not allow me to play videos in Youtube above the resolution 360p. Since now FireFox won't allow me to play YouTube videos from 720p or 1080p anymore. While other browser's allow me to play above 360p up to 4K resolution. What is going on with FireFox this never happen before until the upgrade of FireFox in Manajaro ARM.

I've been through a rough patch with Firefox the past couple of weeks.

Cutting to the chase: I exported all my bookmarks and imported them in a new profile.

But the icons that used to be there aren't.

Not *end of the world*, but just something I noticed.

(I just about shot myself in the foot) Ok, after using one to open a tab and the icon returned. So is that how they get their icons?
