Description

[Tracking Requested - why for this release]:

Both crash signatures started to get noticeable crash volume with Firefox 99 betas which increased for the Firefox 100 ones. All crashes are with 32-bit builds, ~90% of them on Windows 7 - the others on newer Windows versions. The crash submission timestamps indicates this affects users in Asia.
