Since few last betas of Firefox 15 we’re feeling Mozilla browser less snappier than Firefox 14 and it is loading pages slowly, seems the case with more users who submitted feedback to Mozilla about beta version of Firefox as slow, slowly., Its even seems difficult for Mozilla to figure out causes for slowness. We can say from the discussion mentioned in bug below that Firefox 15 is loading pages slowly and consuming more memory than Firefox 14.
Bug 784512 with title “ per input: reports slowness is up about 100% in Firefox 15 vs. 14” says it all . “Mentions of slow in input for Firefox 15 over the last 3 weeks
Running a statistical analysis of word frequencies in input, we have twice as much feedback mentioning slow|slowly|speed|forever in 15 relative to 14.”
Lot of users submitted comments where word “slow” is included in almost every comment
Here is the summary of what users feeling with current beta version of Firefox
- Slow downloads
- Slow page loads
- Frequent crashes
- Flash issues
- High ram usage
- Slow start-up
- Slow games/videos
- Slow search
- Mentions of a number of sites including Facebook, twitter, tumbler, and more
- Slower than previous versions
Flash issues: Is there something to do with Flash Player Protected Mode for Firefox which introduced in Flash 11.3? users feel more crashes happening with Flash Player 11.3 release onwards. It’s true in case of Firefox 14, Adobe recommended to temporarily disable Sandbox for Flash Player. But those issues are fixed, Adobe had already released Flash 11.4 recently.
Slow Search: Blame HTTPS search of Google introduced in Firefox 14, its true that encrypted search returns search results slower than HTTP search.
Slow Startup: We can agree with this Firefox 15 very slow to take off than Firefox 14.
Its true that majority comments are from Windows users, is that Firefox 15 slowness is something platform specific?
Most users mentioned Facebook games and videos (supposed to be from YouTube) loading Slow. With telemetry data too Mozilla doesn’t find out noticeable difference between the two builds. Mozilla looking to get more info if any users can spot performance issue in Firefox 15 that can’t be reproduced in Firefox 14.
We’re hoping Mozilla to find out the causes for performance degradation in Firefox 15 vs. Firefox 14 we want them to fix them in the beta phase, where we’ve Firefox 15 final scheduled to released on 28th of this month.
Are you using Firefox 15 beta? is it slow for you? share with us in comments.
