That is the first line in the Hippocratic Oath. All doctors have to swear to it. All software developers should too.

I made the mistake of letting Firefox on KUbuntu update. It obliterated all my tabs and all my history. There's nothing left. I had a lot of tabs open with intent to use them to update some astronomy instructional activities. I don't know if I'll be able to find them again.

I don't really have a question except to ask: What fresh hell is this? Is it really that hard to just leave things the hell alone? I'm afraid to ever update Firefox again. If everything else wasn't based on Chromium, I'd be out of here.

Also, it looks like something out of Windows 7.

It's all gone. It's a wonder you didn't delete all my bookmarks while you were at it.

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.

So I have an Excel workbook in my onedrive from MS, It was working fine on my firefox browser in my Ubuntu OS, last week it started to delete my cell's information whenever I pressed the enter, tab or arrow keys, I contacted the MS support and they get me to opened the same file on a chrome browser and worked fine... I still want to use my firefox browser but this problem is very annoying, please help me sort it out!!!

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

I use Firefox on Ubuntu 22.04, and my system has 16GB RAM. I have been facing this problem of frequent crashes for the past few months. By crash, I mean not Firefox alone, but the entire system. I use several apps and run several processes that require great compute resources, often simultaneously. I have narrowed the cause of frequent system crashes to Firefox alone; the system rarely crashes when I use other resource-heavy apps. Due to this, I have to restart my system several times a day.

Before this problem arose, I would use multiple tabs (including YouTube, often 10+, close to 20) and multiple windows (2+). Such usage very rarely caused crashes, which is why it is surprising that Firefox now causes the entire system to simply hang sometimes with as low as 3-4 tabs.

I have disabled Hardware Acceleration, refreshed Firefox, even tried disabling WebGL. I also tested it after removing all add-ons, but it still didn't help (I use only 2 add-ons: a simple wide-spectrum ad-blocker and an EPUB reader). Even in troubleshoot mode, Firefox will cause my system to heat up, although it takes some more effort to crash in this case. I use one of the standard themes, so it could not have been the problem.

Many people report Firefox crashes, but in my case, Firefox causes my entire system to crash. How do I fix this issue? Thank you in advance.

Summary: Firefox fails to load many sites, and some will kill the entire browser.

I recently updated from Ubuntu 22.10 to 23.04, which included an upgrade to Firefox. I originally had trouble with tab/window dragging operations causing the entire desktop to crash.

Removing the snap and installing from the Firefox maintained PPA fixed this issue, but a number of others remain. (Detail on this part over here on the ubuntu forums if interested)

Now many google sites simply show the loading error for ever and never recover. Some URLS can kill the browser completely. For example, this one from the Mozilla website: https://support.mozilla.org/en-US/kb/websites-show-spinning-wheel-never-finish-load The error message is attached.

I am happy to perform more tests and provide more diagnostic if it will help. That same URL works fine from the chromium browser on the same desktop systems,as does every other site I've had issues with.

Hello, Firefox friends!

I'm having some issues with Firefox on my Ubuntu system and I'm really hoping someone can help me fix them.

   Problem with Downloads: When I try to download something and click on a link, a new tab opens. But then it immediately closes and nothing downloads.

   Button Issues: Some buttons within Firefox just don't seem to work.

I've tried a few things already:

   Checked for Firefox and Ubuntu updates
   Ran Firefox in Troubleshoot Mode
   No antivirus because I'm on Ubuntu

If anyone has faced similar issues or knows how to fix this, please help!

Thank you so much!

On Ubuntu, drag and drop has broken for me. My mouse cursor does not seem to react to different types of content, like hovering over links. My main problem is that if I highlight a piece of text, or some other content block on a page, and drag it, it does not work as smoothly as it should.

Has anyone else experienced this recently?

I find closing Firefox helps temporarily but within 10-15 minutes the same problem occurs.

I have re-installed Firefox and I am running the latest version. I haven't experienced the problem in Safe Mode.

It only occurs on Firefox and is browser-wide.

Firefox browser crashes whenever uploading or downloading is tried. It seems website independent, and even a trial to start download from an email crashes the browser. Report IDs for some of the submitted crash reports:

UbuntuStudio 22.04 uses the Firefox Snap package by default. The latest automatic update does not display pages correctly in normal mode, but does work correctly on Safe Mode. Snap.io lists only the latest version of Firefox so I was unable to ask snap to revert to the previous release (prior to 5 Mar 24) and by the time I had tried to investigate the previous version was no longer cached. I did not see a way to force a fresh download of firefox from the latest channel on snap.io.

I tried the snap beta channel for v124, but that exhibited the same problems.

I tried adding a symbolic link to colors.css after seeing firefox complaining that it could not be found when started from the command line. That removed the error/warning message but did not clear the problem with normal mode.

I use the en-GB locale extension only. The technical details about my PC are as follows:

• Operating System: Ubuntu Studio 22.04
• KDE Plasma Version: 5.24.7
• KDE Frameworks Version: 5.92.0
• Qt Version: 5.15.3
• Kernel Version: 6.5.0-25-lowlatency (64-bit)
• Graphics Platform: X11
• Processors: 12 × AMD Ryzen 5 7600 6-Core Processor
• Memory: 30.5 GiB of RAM
• Graphics Processor: RAPHAEL_MENDOCINO

I have now downloaded v123 and installed it in my local home directory, and that version is working well. I have removed the firefox channel via snap. It is likely to be a fault in the construction of the snap for v123 that was not present for v122 prior to 5 Mar 24.

Hey guys, I'm using Ubuntu 24.04 with Firefox 124.0 .deb release from this repository: https://launchpad.net/%7Emozillateam/+archive/ubuntu/ppa I enabled "Ask whether to open or save files" from settings. Whenever the Open/Save dialogue is shown and I choose Open, I expect that the file would be opened using the default application. But Firefox asks again to choose the application by which the file (file link?) should be opened. It seems that Firefox is somehow change the way the files are opened through external applications and transformed local file addresses to file://uri/on/disk.

I am running Lubuntu 22.04LTS (have been for months now), with Firefox 130.0.1 installed via the normal vanilla apt.

It was working fine until a few days ago (perhaps after an update, but I can't recall specifically), and then just stopped being able to save anything.

For example, right clicking on an image will bring up "Save As..." as an option, but when I choose that, nothing happens. No prompt to save, nor does the file appear anywhere.

When I choose "Save" as a pulldown on cloud XLSX files...similarly, nothing happens.

When I download something, Firefox is supposed to open up a prompt asking me where I want to save the file but that never opens...nor does the file download.

I am totally baffled.

I just set up a server with linux Ubuntu 24.04 Desktop, with Firefox 129.0.2 included to do some dev and testing work.

Problem: Firefox seems unable to see or open files that are above or outside the user's home dir tree.

The only extra packages installed are the LAMP stack and Google Chrome, which has no problem. (had to have something for A/B testing.)

I've tried entering the url of file:///var/www/index.html, I've tried selecting 'open with...' from the files app, etc. Nothing works.

I can get to the file through http://localserver/index.html with no issues. I've verified permissions on the entire directory tree to the file. Everything from end to end has read permissions for all, 755.

I've checked the following advanced settings: security.sandbox.content.level..............................0 (started at 4, now at 0, no effect or change.) security.fileuri.strict_origin_policy.........................false (default setting as installed.)

I am able to open file:/// and get a dir listing. BUT, if I click on var, it gives "Access to the file was denied." I even tried changing the permissions on /var to 777, but no change.

This seems to be a Firefox only problem, since Google Chrome works where firefox doesn't.

I've spent several hours searching for ways to fix this, all with no success. Does anyone have any idea how to fix this, or even what to look at???

There is (IMHO) some missing functionality / unwanted feature or call it what you like (bug?).

History -> Manage History

select e.g. Last 7 days, right click on Name and select at least two attributes (you can choose from: Tags, Location,Most Recent Visit, Added and Last Modified)

Select the first entry of the list, all displayed fields are selected/highlighted.

Copy (either with the menu or with Ctrl-C) and paste it in your favourite text editor.

Why is only the URL copied? Other fields were also highlighted. Why are they not included?

This is WYSINWYG (what you see is not what you get).

It is possible to export bookmarks as an html file, so why is this not possible with history?

OK, it is possible to query the sqlite3 database directly to get some history info but it's a bit cumbersome.

To do so,

  copy the sqlite (places.sqlite) database to some safe place then open the database (with 'sqlite3 places.sqlite')
  get the history info you are interested in with a sqlite query,
  e.g. select title,visit_count,site_name,url,description,last_visit_date from moz_places where url like '%support%';

But there is no simple (AFAIK) way to convert 'last_visit_date' (an integer) to something human readable.

So either include the whole selection when something is copied (WYSIWYG) or provide export history as an html file.

ps: why is there on option 'other' in the list of 'topics' ? pps: I already posted this comment but it got lost somehow

Hello everyone, i have Linux/Ubuntu software with Firefox browser and for 5 months it has not asked me to update, with it's pop up message. Now it is urgently asking me to update, i have followed the directions given in order to download the latest Firefox version as instructed but with no success. I am downloading it, but it doesn't have an instruction to "run" it. As a consequence, my system is getting slower and slower and i am afraid it will crush! Any ideas? Sooooos!!!

Hi all. I have been using firefox with ubuntu 22.04 for about since when ubuntu 22.04 was released (2022).

On firefox, I usually use the nordpass and tab grouping extensions. For the third or fourth time in a row, firefox has simply vanished from my system from day to night.

I click the icon and nothing happens. I try typing "firefox" in the terminal and get

   Command '/usr/bin/firefox' requires the firefox snap to be installed.
   Please install it with:

   snap install firefox

Even if I accept the bizarreness of snap simply deciding from one day to another that I don't have this package (or did I never have it and never needed it in the first place?) and try "snap install firefox" I get:

   snap "firefox" is already installed, see 'snap help refresh'

After reading the result of "snap refresh help" I decided to "snap refresh" to update all of it's packages. Still, "snap install firefox" and "firefox" keep giving me the same result.

What is happening here?
