Can you install Chromium or SeaMonkey and render that login page with one of those browsers?
(I use SeaMonkey for all websites and for E-Mail, Chromium for 3d-accelerated Google Maps and Firefox for comparisons/testing etc.)
Maybe this way we can determine whether it is the browser’s fault or the website’s fault?
Maybe it is not just a firefox problem (at least it is firefox’s and seamonkey’s).
This happens also with firefox https://susepaste.org/25794383
I can’t see anything in the downloads because it is so small
I have similar problems with LibreOffice when saving a file https://susepaste.org/74392640
Dialog is very small. In this case I can expand it although every time I save something I have to expand it.
I vaguely remember having Firefox- and Seamonkey- specific problems like that while using a broken GTK2 theme way back.
Nowadays, both browsers rely on GTK3 for rendering UI elements, even within a website (prime suspects: textfields, radiobuttons, checkboxes and your standard scrollbar).
On the other hand, Chrome/Chromium and Opera seem to roll their own UI, not sure.
Try using another Gtk3/Gnome default theme (log out and in again to be on the safe side), and if you are so inclined, experiment with the GNOMErunner add-on (I use the add-on to make my SeaMonkey scrollbars to look like my standard KDE/Plasma5 scrollbars).
Right. Both Firefox and Seamonkey use GTK3 … LibreOffice too, true?
Changing Settings-Application Style-Gnome Application Style (GTK) from Breeze to Adwaita solved the problem with Firefox and Seamonkey, It did not change the size of LibreOffice dialogues… I will continue searching.
Adwaita theme is ugly… looks like old Netscape but if it works it works
Both of the images you posted seem similar to me. If it’s just a sizing issue in firefox, just adjust with <CTRL> <+> or <CTRL> <->
I’m not an Opera user, but in an effort to understand/assist, I did install it and then viewed the page directly in both. The firefox default view was smaller initially, but it was easy enough to make the same size by zooming in to match.
What were you using before 15.0? Is 15.0 using an older filesystem for /home/ or /usr/local/ from whatever came before, an old user and old settings, an old 12.1 installation upgraded to 12.2, then 12.3, 13.1, 13.2, 42.x, to 15.0?
Which DE or WM are you using? If using Gnome, Plasma, LXQt, XFCE, Enlightenment, Mate, or Cinnamon, what if you use a different session type to try Firefox? IceWM should already be among your login greeter choices, simple and light weight to test with.
What extensions do you have enabled in Firefox?
How old is your Firefox profile? Does it have a chrome directory in it? If it does, shut Firefox down, rename the chrome directory something else, then try Firefox. chrome is an optional profile directory, so might not exist if the profile isn’t very old. To me this seems to be a …/profiledir/chrome/userChrome.css problem, which could have been caused by an extension, except that it affects your SeaMonkey too. Thus I don’t think this is the problem, but a local system or user data problem.
You may find if you create a virgin login/user that the problem will not manifest in it. This smells like a user settings or system settings problem coming from something in /etc/gtk-3.0/ or ~/.config/gtk-3.0/ or /usr/local/etc/gtk-3.0/. Do any dialogs in Gimp or LibreOffice or some other GTK3 application besides SeaMonkey manifest the same problem?
I have installed OS 15.0 from scratch, but /home is a old /home partition.
How old is the firefox profile? … maybe 20 years … if it may be inherit from Netscape
I have tried from a newly created user and it displays the page well with firefox.
I don’t have a chrome directoy inside firefox profile
Dialog in LibreOffice don’t behave very well either. They display very small too for instance when saving a file… althoug the can be redimensioned.
