Every one of these bugs needs a conscientious and thoughtful person like yourself to determine their merit and engineering destination. You'll quickly get a feel for which bugs are worth an engineer's time. If you can reproduce it, try and beef up the bug report yourself to include the missing information. You may also wish to ask the bug reporter for missing information, refer them to the Bug Writing Guidelines for future bugs, and encourage them to use the Bugzilla Helper . Less experienced bug reporters try to save time by writing a single bug report that raises many different, unrelated issues .
Distinct bugs enable work to proceed in parallel.
When a bug is fixed, it must be verified against a specific test. Bug reports that list multiple conditions and problems are difficult to verify. Bug reports that list multiple bugs may mean that some problems noted do not get addressed. Bug reports that list a single bug are more likely to be resolved in a timely fashion. Less experienced bug reporters will submit bugs that are general complaints about Mozilla, and which do not distill to a fixable bug.
