I am facing this error message while streaming videos. But it doesn't appear in every video, just on some few websites. Things I have tried so far: clearing cache & cookies but failed reinstalled firefox but failed disabled add ons, even started firefox in safe mode but failed reinstalled windows a few days ago but still same.

I have tried using different browsers such as chrome, opera, edge and it works fine in all of them. Is there any solution for this issue?

Hello,

When my VPN client Private Internet Access drops its connection to the VPN server, all the tabs I have open in Firefox say they have crashed. I can restore the pages by simply refreshing, but it didn't used to be like this. This doesn't happen if I turn off wifi or manually disconnect the VPN, only if the VPN drops the connection. Very strange.

My environment: - Mac Mini M1 2020 8GB RAM, 256GB SSD - MacOS Monterey 12.0.1 - PIA MacOS client 3.1.2 (build 06767) - Firefox 94.0.2 (64-bit) -- ublock origin 1.39.0 -- greasemonkey 4.11

Hopefully you can reproduce and fix it.

Hello there

I have a small NAS with various video files on it. Some AVI which work flawless but also some MOV which show but do not play audio.

Other chromium based Browsers manage to do so without any problems therefore it should be possible somehow.

Informations regarding the file: Filetype: MOV Codec: MP4 Base w/ AVC ext (ISO 144496-12:2005) Channels: 2 compressor: sowt Sample rate: 48khz Depth: 24bit Bit rate: 16

It was recorded with a Nikon D3200 camera.

As I am hosting these Files for other people I always get requests on why it does not work in Firefox.

I love Firefox and I want People to use it but such things just make in unnecessarly hard to do so.

I have experienced great business support from the Mozilla team, hope this to be true for home users too.

Thanks beforehand and have a nice evening.

How to liberate the max size of the ".sqlite" file in "storage/default" in "~/.mozilla/firefox"?

Firefox seems to constrain the maximum size of the ".sqlite" file in "storage/default" in "~/.mozilla/firefox" to 10% of the free space of the partition containing the home directory of the user. I need to let the ".sqlite" file grow very large, even larger than the free space of the partition containing my home directory. Therefore, I need the following two points.

1. I would like to disable this 10% constraint. 2. I would like to place this ".sqlite" on an external USB drive (or USB stick) without moving the entire "~/.mozilla/firefox" directory to the external USB drive.

The path of this ".sqlite" contains an enigmatic alphanumeric string and hexadecimal digits, which differ from user to user and from machine to machine, and which may be inappropriate to be exposed to the public. So, I refrain from showing the exact path. Instead, I will describe the path.

The directory "~/.mozilla/firefox" contains a subdirectory whose name ends with ".default-release", which in turn has a subdirectory "storage/default", which still in turn has a subdirectory whose name starts with "moz-extension+++" followed by hexadecimal digits and hyphens (but not followed by "^userContextId"), which still in turn has a subdirectory "idb", which finally contains the file whose name ends with ".sqlite".

The following is a diagram to describe the path. Directories are separated by / as common on Unix-like systems unlike Windows. A sequence of three asterisks (***) indicates an omission of enigmatic string.

   ~/.mozilla/firefox/
     ***.default-release/
       storage/default/
         moz-extension+++***/  not followed by ^userContextId
           idb/
             ***.sqlite


Firefox seems to constrain the maximum size of this ".sqlite" file to 10% of the free space of the partition containing the home directory of the user.

I replaced the "idb" directory with a symlink named "idb" which points at a directory (which is also named "idb") on an external USB drive. That is, I deleted the "idb" directory from the partition containing the "~/.mozilla/firefox" directory, and created a symlink named "idb" in the place of the old "idb" directory.

Then, I successfully let Firefox write data into the new ".sqlite" file on the external USB drive. However, Firefox continues to constrain the maximum size of this ".sqlite" file to 10% of the free space of the partition containing the home directory of the user. Even after the diversion by symlink, the basis of the constraint is still the partition containing the home directory of the user (instead of the external USB drive), of which 10% is the max size of the new ".sqlite" file residing on the external USB drive.

I like neither the 10% constraint itself nor the basis of constraint being the partition containing the home directory of the user.

How can the 10% constraint be disabled? I would like the only limitation for the size of the ".sqlite" file to be the free space of the external USB drive.


By the way, for those who want to know why I care about this ".sqlite" file, I will explain as follows. There is a certain download manager which is an addon or extension of Firefox. In its multithread mode, this download manager divides the desired file into several parts, and downloads all the parts simultaneously. In certain circumstances, the multithread mode is several times faster than the single-thread mode. This download manager downloads all the parts of a file into the ".sqlite" file first, and then assembles them into a final big file in the Downloads folder or whichever directory that the user specifies.

In my use case, 10% of the free space of the partition containing my home directory is too small to receive big files. I wish this download manager could download the multi-parts into an external USB drive in a manner that Firefox does not impose any constraint. However, this download manager cannot let the user specify where the multi-parts should be downloaded to. It downloads the multi-parts into only the ".sqlite" file and nowhere else; and Firefox imposes the 10% constraint on the ".sqlite" file. The user can specify the destination of only the final file assembled from the multi-parts.

Anyway, I need to disable the 10% constraint. But how?

Thank you in advance.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. How do I get the autofill to start working again?

I am running Firefox 94.0 in a couple of Linux Mint systems.

My main desktop computer, with a 3.8 GHz 6-core AMD Ryzen 5 processor on an MSI B450-A PRO MAX MB with 16 GB RAM, has had Linux Mint 19.3 installed for over a year. Just today, Firefox, which has also been installed in this OS for a long time, exhibited extreme slowness. I did an online search, and found that the slowness was cured by using the Troubleshoot Mode, but none of the suggestions I found solved the problem in normal mode. So, I went into Settings and turned off hardware acceleration. That solved the problem, somewhat ironically. The hardware acceleration seemed to accomplish deceleration instead. So my browser works, but there is something wrong with hardware acceleration in Firefox.

On a new install of Linux Mint 20.04, I recently experienced frequent crashing of Firefox just after clicking on a link. I tried online solutions, which didn't help, but then I turned off - - guess what - - hardware acceleration, and no more crashes. That is what motivated me to turn off hardware acceleration in Firefox on my Linux Mint 19.3 machine today.

I don't really have a problem to solve, but I don't know of a better place to submit a bug report, so I am hoping you will pass this on to the developers.

Earlier, when I activated the search field with the Ctrl + K key combination, it was possible to go far back, by rolling back to the previous words (characters). After the update, it almost stopped working. I press Ctrl + Z and nothing happens. As if the browser "forgot" which characters were entered earlier. I haven't made any changes to the settings after the update. Help.

After an update earlier this year I began having the cursor freeze when I was typing in any text field such as in Gmail compose.

Even as I type in this field it has occurred. I was using backspace to edit out a phrase. The cursor remained at the left as ~15 characters were removed. Then both the keyboard and cursor commands ceased to be executed. For ~3 minutes the screen remains locked with the cursor separated from the trailing text by those 15 blank spaces. Then all "stored commands" are executed. During the lockup I am able to use touchscreen to open all other applications, but can not close.

I am in 94.0.2 as I use your auto update setting. I used "refresh" without remedy. I even uninstalled Foxfire, closed the laptop, restarted, and performed a fresh install. The only plugins are the one you install and one from google.

I am now using another browser for all my email work! Frankly, it is apt to become my default if I cannot resolve this aggravation.

Looking forward to your suggestions/tips. Let me know if I can supply further information.

Peace/Out
