I noticed during a firmware download with the file extension .DAT that Firefox removed the extension. The file was not recognizable during an attempted firmware upgrade afterward. This is a new issue occurring sometime in the past several months, since last firmware update. Firefox preferences are set to download .DAT files. No other settings are listed for that file extension. I verified the issue points toward Firefox by checking the download with another web browser which completed the download with the extension.

Hello, I have been using Firefox as my main browser for more than a decade. One could say i am some Mozilla fanboy, having convinced many of my friends and relatives to use Firefox instead of any chrome based options (Which there are to many these days). It struck me today, as i was reworking some workflow elements in many programs i use daily, that it is impossible to change any key binding in Firefox anymore. I know it has been a while now, and i searched all over the web for an answer or a solution, but at this point it is clear that other than going in the code and recompiling Firefox manually, it is not possible. I stumbled upon the (only) extension that allows to change some shortcuts, but the two that i wanted to change are impossible to configure from it, being disabling only f12 as i would use it for other things but i do not want to lose the dev console and also ctrl+L to open the address bar, it is quite inconvenient and would much prefer to use ctrl+spacebar as it matches many other bindings i am using with other software. There have been many other features that were changed in the recent years that made me start to look for an alternative, as i see features melting away almost as quickly as the user base of the product.

I do understand that one person's problem is not going to change the way a big piece of software is working, but i am wondering, why are the users losing such features as basic as customizing key bindings in a piece of software that used to be so incredibly customizable in the past? Why is the only viable option to anything chrome based losing it's edge over the competition? Is Firefox v150 be based on the chromium engine or will it die before?

Thank you in advance, and no, i don't need the link to the shortcut page, i already have it.

The present configuration of Bookmarks:

Both "areas" of Bookmarks are linked, deleting from one will update the other. Neither are isolated personal storage areas for selected bookmarks of the user's choosing. You can't keep/delete one bookmark in one area (Bookmarks toolbar and/or hamburger icon > Bookmarks) without the action being correspondingly reflected in the other area.

Now previously I could go to the hamburger Bookmarks, create and delete without my tool bar Bookmarks being effected. Any chance of this happening again please?

Hi everybody, I never cleared my browsing history so far, because I often need to know which websites I already visited when I perform a research on Google. Having the previously visited URLs shown in a different colour is useful for my work.

However, I am wondering whether this huge amount of data could affect the browser speed and memory usage. More specifically, I have a few questions:

1) Out of curiosity, in which file of Firefox installation folder the history is saved, and where can I find it? 2) Do you think it is possible to clear ALL the browsing history, except for one specific URL? 3) Could a cluttered browsing history file affect negatively my browser performance?

Many thanks in advance for your help, Elisa

Not sure what happened. I thought I clicked on an update and suddenly Firefox refused to open. I had to re-install Firefox and not sure how to get my preset tabs and history back. I could really use your help as I'm not the most computer literate person and also thanks in advance. Right now everything is in pink, not my fav, to differentiate from what I had before. I deleted my original firefox icon on my taskbar as It would not open or give me internet access.

Since updating to Firefox 102.0, text is not displaying correctly or at all on number of sites, including Gmail and Google.ca. I tried starting FF in Troubleshooting mode, and it solved the problem, but when I went through the steps in the "Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems" article, that didn't fix the issue once I left Troubleshooting mode. I also tried to reinstall Firefox and to refresh Firefox, which I now really regret doing since it didn't solve the issue and my extensions are not working as they did prior to the refresh when I reinstalled them. Wikipedia seems to be displaying text fine, but for many websites the text is just not visible at all. At the moment, I can't even type or paste text into an email...it displays as boxes with numbers in them (not sure what they're called). Oddly, I can see the text in the email preview, but not when I open the email (then it's just blank). Thanks for any help you can provide!
