Description of problem: Firefox on Fedora 22 is putting more than necessary vertical white space above a line with an inline MathML equation. To be more specific enough extra space to fit another line (with normal spacing above and below). Version-Release number of selected component (if applicable): firefox-45.0-4.fc22.x86_64 How reproducible: Always. Steps to Reproduce: Save the following text as an xml file and view in Firefox browser on Fedora 22: <?xml version='1.0'?> <html xmlns='http://www.w3.org/1999/xhtml' xmlns:math='http://www.w3.org/1998/Math/MathML' > <body> This line comes before the inline equation: <br/> Line with the inline equation <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"> <mi>y</mi> <mo>=</mo> <mi>f</mi> <mo>(</mo> <mi>x</mi> <mo>)</mo> </math> . <br/> This line comes after the inline equation. </body> </html> Actual results: This line comes before the inline equation: Line with the inline equation y = f ( x ). This line comes after the inline equation. Expected results: This line comes before the inline equation: Line with the inline equation y = f ( x ). This line comes after the inline equation. Additional info: This extra space does not appear on Windows with Firefox 43.0.1.
Can you please test mozilla binary from mozilla.com?
(In reply to Martin Stransky from comment #1) > Can you please test mozilla binary from mozilla.com? I am not sure what you mean. Is there a web page that has a firefox binary, I can downalod, that should work with Fedora 22 (and not conflict with the one that dnf install on the system) ? If so, what is the corresponding web address ?
Yes, you can download the binary version here: https://www.mozilla.org/en-US/firefox/all/#en-US just extract it to some dir and run.

I download the 64 bit Linux version of the link above and got the file firefox-46.0.tar.bz2 I then unzipped and untared the file and got a directory. In the directory I executed ./run_mozilla.sh firefox When I check the version of the resulting firefox program I get 45.0 not 46.0. I tried exiting all my Firefox window and rerunning the command above and still got version 45.0. When I load example xml file above, I get the same results as before; i.e., there is an extra line of white space.
I have verified that the example gives the expected results (no extra line) on the following system: >uname -a Linux brad-ubuntu14 3.13.0-44-generic #73-Ubuntu SMP Tue Dec 16 00:22:43 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux ~>firefox --version Mozilla Firefox 47.0 It still gives the extra line on the following system: uname -a Linux brad-home 4.1.3-200.fc22.x86_64 #1 SMP Wed Jul 22 19:51:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux firefox --version Mozilla Firefox 46.0.1
