Why cannot see Mozilla browser if I set it as a default browser?

Using Ubuntu: User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:134.0) Gecko/20100101 Firefox/134.0

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

I upgraded Firefox using Ubuntu's apt update, apt dist-upgrade. The upgrade process said my version is 134.0.1 but when I look on the Help button is says my version is 125.0.2. How do I upgrade to 134.0.1?

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?

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

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

Firefox does not seem to be properly configured for Wayland on KDE Plasma 6.x systems. The generic "Wayland" logo appears in task switcher instead of the Firefox logo. Firefox is the only program I have with this issue. Setting desktop name (org.mozilla.firefox) as a property in the Window and Application Manager settings does not resolve the issue.

i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

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???

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.

Hello

Recently I've upgraded from Kubuntu 24.04 to 24.10. I'm almost sure that the minimize/restore buttons were available in my Firefox after the system upgrade. For the last few days I can see they are missing - please see attached images.

I can partly fix the problem by going to Settings->More tools -> Customize toolbar and selecting "Title Bar" checkbox. In that case I have the title bar displayed with all 3 button (minimize, restore, close).

But I would like to have the default behavior: title bar is turned off and the mentioned 3 buttons be visible in the tab bar.

How to have those buttons in the tab bar when the title bar is turned off?

For the past few months, the browser will no longer download any files. The only diagnostic that I can see is failed when the download is attempted. I have refreshed firefox and the problem remains. Chrome can download without any problems, but I used firefox for many years and wish to continue.

Browsing works well on my Ubuntu/Linux 22.04.5 laptop except one site. Images are not loading. I can see it has js-errors which might be related. And that may be because some js files are being blocked. The site does work on my iphone though. And using Browserstack I can see it works with other OS.

The site is: knowledgecottonapparel . com

I've verified that others using Linux has the same issue, https://askubuntu.com/questions/1526728/issue-with-specific-site

Machine: Dell Inspiron 15 5567 CPU: Intel i5-7xxx Op Sys: Ubuntu 24.04.1 Firefox version: Flathub 130.0

For the past 2 weeks Firefox has been repeatedly crashing soon after going on to certain sites or trying to apply my 2FA authenticator add-on.

Suddenly there's a screen shudder and a new window opens, inviting me to submit a crash report. See attached image.

I do not believe that this is down to Ubuntu 24.04 upgrade done at end of August.

But it's enough for me to largely go over to Chromium and Firefox Dev Ed.

If Mozilla don't act on this crashing I can see its market being lost fairly fast.
