Firefox in 19.10 is kind of slow to get ready

Coeur-Noir · March 27, 2020, 9:11pm

Hi,

I recently installed a 19.10 UbuntuBudgie. I was using 18.04 ago.

Since this new installation I’ve noticed Firefox is kind of slow to « start » :
⋅ I can launch Firefox but it’s unresponsive for a moment ( no blinking cursor anywhere )
⋅ then cursor eventually appears in address bar but blinking slowly and not usable,
⋅ still, clicking anywhere has no effect, or effect delayed much later,
⋅ a moment later, cursor blinks at its usual pace and Firefox becomes responsive as expected.
The whole process takes 30 seconds to 1 minute and Firefox runs rather ok later on with some slow moments though.

Same behavior in safe-mode ( without any FF addons ).


(firefox:17653): LIBDBUSMENU-GTK-CRITICAL **: 21:52:24.565: dbusmenu_menuitem_property_set_shortcut: assertion 'gtk_accelerator_valid(key, modifier)' failed

(firefox:17653): LIBDBUSMENU-GTK-CRITICAL **: 22:07:18.480: dbusmenu_menuitem_property_set_shortcut: assertion 'gtk_accelerator_valid(key, modifier)' failed
django@ASGARD:~$ firefox --safe-mode 

(firefox:19093): LIBDBUSMENU-GTK-CRITICAL **: 22:08:02.177: dbusmenu_menuitem_property_set_shortcut: assertion 'gtk_accelerator_valid(key, modifier)' failed

I use Budgie applets : pixel-saver and global menu. Guess it’s related ?
→ maybe not related, even without these budgie applets, FF still shows the exact same error.
[ edit 2020-04-04 ] → my big mistake here → one has to logout / login back to session after each modification on applets / panels !!!

Well I think we can start there. Did you test that?

Coeur-Noir · March 27, 2020, 9:38pm

I edited my post - meaning I have tested without applets and problems ( message in terminal + slowness ) still there

Nota also, I did not have those problems in UBudgie 18.04.

@Coeur-Noir thanks! I’ll have a look. This is likely upstream though (suspect based on URLs).

Appreciate the links.

Coeur-Noir · March 31, 2020, 8:34pm

First link is old, 2011.

Second is mine, 2020-03-29.

And no surprise, I don’t have these problems in 16.04 with FF74.

Disabling hardware acceleration in FF does not change anything.

Another example of « glitch » is in twitter, when clicking on a picture, it kind of flashes / gets half transparent ( maybe more related to SuperTuxKart in 18.04 : flickering shadows with intel i915 )

Coeur-Noir · April 2, 2020, 4:02pm

Nobody’s noticed the same ?

On everyday’s usage it becomes a real pain…

bashfulrobot · April 2, 2020, 4:23pm

I have not seen this at all. FF opens up almost immediately for me. (See the GIF). I had been trying to replicate - but I can’t seem to mimic your behavior.

Coeur-Noir · April 2, 2020, 4:25pm

Mmm… I’ll try with a new profile.

Coeur-Noir · April 2, 2020, 5:35pm

…same with empty FF profile.

Problem here is, as long as Firefox has not finished its starting, all interactions with Budgie desktop are also slowed down ( if I click anything in panels, it will react only after FF is completely ready ).

Coeur-Noir · April 3, 2020, 12:15am

Adding some info, as did there https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1870450

Any thought about these corrupt or missing mentions ?

ruwe · April 3, 2020, 1:00am

Checked the twitter flickering pictures issue but can’t reproduce it either … everything normal with Firefox at this part of the quarantine…

Coeur-Noir · April 3, 2020, 3:25am

Regarding slow starting and LIBDBUSMENU-GTK-CRITICAL → I don’t have them if I launch Firefox as downloaded from Mozilla site as a standalone.

zilexa · April 3, 2020, 11:28am

Firefox starts instantly here even after a new 19.10 clean install. On a Core i3-9100.

Coeur-Noir · April 3, 2020, 1:38pm

Please launch Firefox from terminal and see if any error message.

Launch is fast - but with a frozen unresponsive whole interface for a long moment.

It seems there is a problem in my installation but sudo apt install --reinstall firefox did not help.

Since Firefox downloaded from Mozilla’s page works without error, I have some hope to find out what went wrong ( file omni.ja ? )

If of any interest, here are my installed dbus packages :

Is it normal to find libdbusmenu-gtk4:amd64 already installed by default ?

Going on on my experimentations with « pure » FF from Mozilla, I’ve noticed :
⋅ it does not throw any errors regarding libdbusmenu ( even with my older profile⋅s )
⋅ but it does not export app-menu to Budgie global menu applet…

And going further, is it normal there is no .dbus folder in any of users’ personal folder of Ubuntu Budgie 19.10 ???

Edit,later : on 20.04 tested on live usb, there is a .dbus folder…

bashfulrobot · April 4, 2020, 12:42am

Have you tried reinstalling Firefox by chance?

Coeur-Noir · April 4, 2020, 12:44am

Yes, I did try. Not better.

Weird. Any thought about .dbus folder missing ?

bashfulrobot · April 4, 2020, 12:48am

I went poking around, and I found a very similar bug (sqllite extension) on regular Ubuntu (and not just budgie).

https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1850597

Have you tried to see if there are any bugs on the Mozilla tracker for this?

Coeur-Noir · April 4, 2020, 12:54am

Not the same problem, I have never had errors regarding profiles.

I even have tested with different profiles, empty profiles, new profiles.

I always have the (firefox:17653): LIBDBUSMENU-GTK-CRITICAL **: 21:52:24.565: dbusmenu_menuitem_property_set_shortcut: assertion 'gtk_accelerator_valid(key, modifier)' failed error message in terminal. This added to the fact I don’t have .dbus folder in my personal folder sounds not good and related…

And also this in dmesg :

[  607.797925] budgie-panel[1671]: segfault at 0 ip 00007ff290bc8e57 sp 00007ffd2ac8ba00 error 4 in libgtk-3.so.0.2404.8[7ff2909ea000+36e000]
[  607.797930] Code: ef f8 ff ff 41 01 c5 83 c2 01 44 89 6c 24 24 41 39 d6 75 df 8b 4c 24 18 85 c9 7e 69 31 db 0f 1f 44 00 00 49 8b 3c 24 48 89 fe <4c> 8b 3f e8 d1 cf e2 ff 49 89 04 24 4c 89 ff e8 b5 f8 ff ff 4d 85

Bad chance ?

Or this is much longer :

django@ASGARD:~$ cat /var/log/syslog | grep -i error

→ here → https://paste.ubuntu.com/p/vB9MDKbZCb/
with many mention of gdbus, ayatana, unity, budgie-panel, gtk…

The constant accelerator messages is a fix in 20.04

If you create a new account with no changes do you have the same firefox launch issues
